本发明涉及通信技术领域，尤其涉及一种降低无线干扰的方法和无线终端。The present invention relates to the field of communication technology, in particular to a method for reducing wireless interference and a wireless terminal.
背景技术Background technique
随着消费类电子产品越来越丰富，越来越多的无线模块集成到一个电子产品上。目前，一些移动多媒体产品，比如，手机，掌上电脑PAD，多功能播放器等，都集成了多种通信制式。其中，多种通信制式包括：全球定位系统(Global Positioning System，GPS)，全球移动通讯系统(Global System of Mobile communication，GSM)，近距离无线通讯技术(NearField Communication，NFC)等，因此，当多种通信制式集成在一台移动终端上应用时，必然导致各个与通信制式相对应的无线系统之间进行相互干扰，从而出现如何相互共存问题。比如，GSM与码分多址(Code Division Multiple Access，CDMA)，GSM与GPS等组合应用，都会导致各个天线系统之间相互干扰，进一步降低了该系统中各模块的接收性能，并会出现通信不畅，视频通话停滞或者网络视频画面停滞等问题，从而制约了移动终端产品的发展，还降低了用户体验度。As consumer electronic products become more and more abundant, more and more wireless modules are integrated into one electronic product. At present, some mobile multimedia products, such as mobile phones, PDAs, multi-function players, etc., are integrated with multiple communication systems. Among them, a variety of communication standards include: Global Positioning System (Global Positioning System, GPS), Global System of Mobile Communication (Global System of Mobile communication, GSM), short-range wireless communication technology (NearField Communication, NFC), etc., therefore, when more When multiple communication standards are integrated and applied on a mobile terminal, it will inevitably lead to mutual interference between the wireless systems corresponding to the communication standards, and thus the problem of how to coexist with each other arises. For example, the combined application of GSM and Code Division Multiple Access (CDMA), GSM and GPS will cause mutual interference between each antenna system, further reduce the receiving performance of each module in the system, and cause communication problems. Unsmooth, stagnation of video calls or stagnation of network video images, etc., thus restricting the development of mobile terminal products and reducing user experience.
目前，为了减少各个无线系统之间的相互干扰，一般采用以下方法：(1)通过增加各个无线系统的天线间的距离，同时尽量调整各天线的辐射方向性，降低各个无线系统之间的干扰。(2)通过软件规避处理，假如A,B两个无线系统同时工作时，只要A系统处于发射状态，则将B系统的接收机关闭，此时B系统无接收信号进入其接收机进行解调，避开A系统发射带来的干扰。At present, in order to reduce the mutual interference between various wireless systems, the following methods are generally adopted: (1) By increasing the distance between the antennas of each wireless system, and at the same time adjusting the radiation directionality of each antenna as much as possible, the interference between each wireless system is reduced . (2) Through software circumvention processing, if two wireless systems A and B are working at the same time, as long as system A is in the transmitting state, the receiver of system B will be turned off. At this time, no received signal of system B will enter its receiver for demodulation , to avoid the interference caused by the launch of the A system.
但是，上述方法(1)的缺点是：因为电子产品本身不可能做的很大，而且天线方向性并不容易在同一个参考地的情况下进行大幅改变，当出现多个无线系统时，更不容易保证各个无线系统的天线之间都能很好避开相互之间的最大辐射角，所以各个无线系统的天线之间的隔离度通过空间距离的改变是非常有限的；上述方法(2)的缺点是：当A系统处于发射状态时，B系统不能进行接收解调时，必然导致B系统的接收数据丢失，对B系统的误码率，丢包率等造成影响，降低了B系统的接收性能，影响到用户体验甚至掉网。However, the disadvantage of the above method (1) is: because the electronic product itself cannot be made very large, and the antenna directivity is not easy to change greatly under the same reference ground, when multiple wireless systems appear, more It is not easy to ensure that the antennas of each wireless system can well avoid the maximum radiation angle between each other, so the isolation between the antennas of each wireless system is very limited through the change of the spatial distance; the above method (2) The disadvantage is: when system A is in the transmitting state, when system B cannot receive and demodulate, it will inevitably lead to the loss of received data of system B, which will affect the bit error rate and packet loss rate of system B, and reduce the performance of system B. Receiving performance affects user experience and even drops the network.

本发明公开了一种降低无线干扰的方法和无线终端，通过获取无线终端的第一无线系统的执行状态、以及无线终端的第二无线系统的执行状态，当第一无线系统处于发射状态，第二无线系统处于接收状态，且第一无线系统对第二无线系统的干扰超过第二无线系统所预设的干扰阈值时，基带系统向无线终端的调谐电路系统发送第一指令，第一指令用于指示调谐电路系统将第一无线系统的第一工作频点调节为第二工作频点；第一无线系统工作在第二工作频点时对第二无线系统的干扰，小于第一无线系统工作在第一工作频点时对第二无线系统的干扰，从而实现了在降低误码率的同时，降低了无线系统之间的干扰。The invention discloses a method for reducing wireless interference and a wireless terminal. By acquiring the execution state of the first wireless system of the wireless terminal and the execution state of the second wireless system of the wireless terminal, when the first wireless system is in the transmitting state, the second When the second wireless system is in the receiving state, and the interference of the first wireless system to the second wireless system exceeds the preset interference threshold of the second wireless system, the baseband system sends a first instruction to the tuning circuit system of the wireless terminal, and the first instruction uses Instruct the tuning circuit system to adjust the first operating frequency of the first wireless system to the second operating frequency; when the first wireless system operates at the second operating frequency, the interference to the second wireless system is less than that of the first wireless system The interference to the second wireless system at the first working frequency point, thereby reducing the interference between wireless systems while reducing the bit error rate.
图1为本发明实施例一提供的降低无线干扰的方法的流程图。如图所示，本发明实施例具体包括以下步骤：FIG. 1 is a flowchart of a method for reducing wireless interference provided by Embodiment 1 of the present invention. As shown in the figure, the embodiment of the present invention specifically includes the following steps:
步骤110，无线终端的基带系统获取所述无线终端的第一无线系统的执行状态、以及所述无线终端的第二无线系统的执行状态，所述执行状态包括接收状态和发射状态。另外，所述执行状态还包括关闭状态。其中，基带系统、第一无线系统和第二无线系统位于同一个无线终端上，该无线终端还包括调谐电路。基带系统分别控制第一无线系统和第二无线系统的执行状态。调谐电路负责调节第一无线系统或第二无线系统的谐调频点。Step 110, the baseband system of the wireless terminal acquires the execution state of the first wireless system of the wireless terminal and the execution state of the second wireless system of the wireless terminal, the execution state includes a receiving state and a transmitting state. In addition, the execution state also includes a closed state. Wherein, the baseband system, the first wireless system and the second wireless system are located on the same wireless terminal, and the wireless terminal also includes a tuner circuit. The baseband system respectively controls the execution states of the first wireless system and the second wireless system. The tuning circuit is responsible for adjusting the tuning frequency point of the first wireless system or the second wireless system.
进一步地，该步骤110中，无线终端的基带系统通过所述基带系统和所述第一无线系统之间的第一反馈系统获取所述第一无线系统的执行状态，并通过所述基带系统和所述第二无线系统之间的第二反馈系统获取所述第二无线系统的执行状态。Further, in step 110, the baseband system of the wireless terminal obtains the execution status of the first wireless system through the first feedback system between the baseband system and the first wireless system, and obtains the execution status of the first wireless system through the baseband system and the first wireless system A second feedback system between the second wireless system acquires an execution status of the second wireless system.
步骤120，当所述第一无线系统处于所述发射状态，所述第二无线系统处于所述接收状态，且所述第一无线系统对第二无线系统的干扰超过所述第二无线系统所预设的干扰阈值时，该无线终端的基带系统向所述无线终端的调谐电路系统发送第一指令；所述第一指令用于指示所述调谐电路系统将所述第一无线系统的第一工作频点调节为第二工作频点；所述第一无线系统工作在第二工作频点时对第二无线系统的干扰，小于所述第一无线系统工作在第一工作频点时对第二无线系统的干扰。其中，表示第二无线系统所预设的干扰阈值大小的物理指标是dB,比如，第二天线系统的接收性能为-105dB，当受到第一天线系统的干扰为5dB，则第二天线系统的接收灵敏度就下降到了-100dB，如果第二天线系统的最低要求的接收灵敏度是-100dB即第二天线系统接收到的信息强度低于-100dB时就不能正确解调出用户的信息，所以第二天线系统可以将预设的干扰阈值设为5dB。Step 120, when the first wireless system is in the transmitting state, the second wireless system is in the receiving state, and the interference of the first wireless system to the second wireless system exceeds that of the second wireless system When the preset interference threshold is reached, the baseband system of the wireless terminal sends a first instruction to the tuning circuit system of the wireless terminal; the first instruction is used to instruct the tuning circuit system to use the first The working frequency is adjusted to the second working frequency; the interference to the second wireless system when the first wireless system works at the second working frequency is smaller than the interference to the second wireless system when the first wireless system works at the first working frequency Two wireless system interference. Wherein, the physical index representing the preset interference threshold of the second wireless system is dB, for example, the receiving performance of the second antenna system is -105dB, when the interference by the first antenna system is 5dB, then the second antenna system The receiving sensitivity drops to -100dB. If the minimum required receiving sensitivity of the second antenna system is -100dB, that is, when the information intensity received by the second antenna system is lower than -100dB, the user's information cannot be demodulated correctly, so the second The antenna system can set the preset interference threshold to 5dB.
具体地，基带系统控制第一无线系统和第二无线系统同时工作后，会对第一无线系统和第二无线系统的执行状态进行检测，目的是检测第一无线系统和第二无线系统之间是否互相干扰，但是，每个无线系统都有自己的正常所能承受的干扰门限即预设的干扰阈值，只有超过该干扰阈值时，说明第一无线系统和第二无线系统之间的干扰超过系统所述承受的干扰门限，必须对第一无线系统和第二无线系统进行相应的处理。比如，当第一无线系统处于发射状态和第二无线系统处于接收状态，且所述第一无线系统对第二无线系统的干扰超过所述第二无线系统所预设的干扰阈值时，说明第一无线系统对第二无线系统的干扰超过了第二无线系统所能承受的干扰门限，将严重影响第二无线系统的接收性能，故基带系统向调谐电路系统发送第一指令，该第一指令用于指示所述调谐电路系统将所述第一无线系统的第一工作频点调节为第二工作频点，其中，所述第一无线系统工作在第二工作频点时对第二无线系统的干扰，小于所述第一无线系统工作在第一工作频点时对第二无线系统的干扰，从而通过改变第一无线系统的工作频点的方法，实现了降低对第二无线系统的干扰的目的。Specifically, after the baseband system controls the first wireless system and the second wireless system to work at the same time, it will detect the execution status of the first wireless system and the second wireless system, in order to detect the difference between the first wireless system and the second wireless system. Whether they interfere with each other, however, each wireless system has its own interference threshold that can normally be tolerated, that is, the preset interference threshold. Only when the interference threshold is exceeded, it means that the interference between the first wireless system and the second wireless system exceeds The interference thresholds that the system can withstand must be dealt with accordingly for the first wireless system and the second wireless system. For example, when the first wireless system is in the transmitting state and the second wireless system is in the receiving state, and the interference of the first wireless system to the second wireless system exceeds the preset interference threshold of the second wireless system, the second The interference of a wireless system to the second wireless system exceeds the interference threshold that the second wireless system can withstand, which will seriously affect the receiving performance of the second wireless system. Therefore, the baseband system sends a first instruction to the tuning circuit system. The first instruction It is used to instruct the tuning circuit system to adjust the first operating frequency point of the first wireless system to the second operating frequency point, wherein, when the first wireless system operates at the second operating frequency point, the second wireless system The interference is less than the interference to the second wireless system when the first wireless system works at the first operating frequency, so that the interference to the second wireless system is reduced by changing the operating frequency of the first wireless system the goal of.
进一步地，步骤120之后，还包括：基带系统定期获取所述无线终端上的第一无线系统和第二无线系统的执行状态，并当所述第一无线系统处于所述发射状态且所述第二无线系统处于所述关闭状态时，向所述调谐电路系统发送第二指令；所述第二指令用于指示所述调谐电路系统将所述第一无线系统的第二工作频点调节为所述第一工作频点。Further, after step 120, it also includes: the baseband system periodically obtains the execution status of the first wireless system and the second wireless system on the wireless terminal, and when the first wireless system is in the transmitting state and the second wireless system When the second wireless system is in the off state, send a second instruction to the tuning circuit system; the second instruction is used to instruct the tuning circuit system to adjust the second operating frequency of the first wireless system to the desired Describe the first working frequency point.
具体地，基带系统会定期或一直检测第一无线系统和第二无线系统的执行状态，当第一无线系统处于发射状态和第二无线系统处于关闭状态时，说明第一无线系统和第二无线系统不再同时工作，则此时可以恢复第一无线系统原来的工作频点，故基带系统向所述调谐电路系统发送的第二指令，所述第二指令用于指示所述调谐电路系统恢复所述第一无线系统的工作频点，所述调谐电路系统根据所述第二指令将所述第一无线系统的第二工作频点调节为所述第一工作频点，即恢复了第一无线系统原来的工作频点。Specifically, the baseband system will periodically or always detect the execution status of the first wireless system and the second wireless system. When the first wireless system is in the transmitting state and the second wireless system is in the off state, it indicates that the first wireless system and the second wireless system The system is no longer working at the same time, then the original operating frequency of the first wireless system can be restored at this time, so the baseband system sends the second instruction to the tuning circuit system, and the second instruction is used to instruct the tuning circuit system to resume the operating frequency of the first wireless system, the tuning circuit system adjusts the second operating frequency of the first wireless system to the first operating frequency according to the second instruction, that is, restores the first The original working frequency of the wireless system.
进一步地，本发明实施例提供的降低无线干扰的方法还包括：当所述第一无线系统处于接收状态，第二无线系统处于发射状态，且所述第二无线系统对所述第一无线系统的干扰超过所述第一无线系统所预设的干扰阈值时，向所述调谐电路系统发送工作频点第三指令，所述第三指令用于指示所述调谐电路系统将所述第二无线系统的第三工作频点调节为第四工作频点，所述第二无线系统工作在第四工作频点时对第一无线系统的干扰，小于所述第二无线系统工作在第三工作频点时对第一无线系统的干扰。该方法中是第一无线系统处于接收状态和第二无线系统处于发射状态，而步骤120中第一无线系统处于发射状态和所述第二无线系统处于接收状态，这是两者的最大区别，但是实现的方法相同，在这里不再赘述。Further, the method for reducing wireless interference provided by the embodiment of the present invention further includes: when the first wireless system is in the receiving state, the second wireless system is in the transmitting state, and the second wireless system is in the first wireless system When the interference of the first wireless system exceeds the interference threshold preset by the first wireless system, a third instruction of the operating frequency point is sent to the tuning circuit system, and the third instruction is used to instruct the tuning circuit system to use the second wireless system The third working frequency of the system is adjusted to the fourth working frequency, and the interference to the first wireless system when the second wireless system works at the fourth working frequency is less than that of the second wireless system working at the third working frequency. Interference with the first wireless system at point time. In this method, the first wireless system is in the receiving state and the second wireless system is in the transmitting state, but in step 120, the first wireless system is in the transmitting state and the second wireless system is in the receiving state, which is the biggest difference between the two, However, the implementation method is the same and will not be repeated here.
进一步地，基带系统会定期或一直获取第一无线系统和第二无线系统的执行状态，当所述第一无线系统处于关闭状态，所述第二无线系统处于发射状态时，说明第一无线系统和第二无线系统不再同时工作，则此时可以恢复第二无线系统原来的工作频点，故向所述调谐电路系统发送第四指令，所述第四指令用于指示所述调谐电路系统将所述第二无线系统的第四工作频点调节为所述第三工作频点。Further, the baseband system will periodically or always obtain the execution status of the first wireless system and the second wireless system, and when the first wireless system is in the off state and the second wireless system is in the transmitting state, it means that the first wireless system and the second wireless system no longer work at the same time, then the original operating frequency of the second wireless system can be restored at this time, so a fourth instruction is sent to the tuning circuit system, and the fourth instruction is used to instruct the tuning circuit system adjusting the fourth operating frequency point of the second wireless system to the third operating frequency point.
上述方法中只涉及第一无线系统和第二无线系统，即无线终端只包括两个无线系统，比如，GSM与GPS，同时该两个无线系统共用一个调谐电路系统，通过同一个调谐电路系统调节第一无线系统或第二无线系统的工作频点，从而降低第一无线系统和第二无线系统之间的干扰。其中，两个无线系统也可以不用共用一个调谐电路系统，而是每个无线系统配置一个调谐电路系统，通过自身配置的调谐电路系统调节系统的工作频点，从而也能实现降低第一无线系统和第二无线系统之间的干扰的目的。The above method only involves the first wireless system and the second wireless system, that is, the wireless terminal only includes two wireless systems, such as GSM and GPS, and at the same time, the two wireless systems share a tuning circuit system, and are adjusted through the same tuning circuit system. The working frequency point of the first wireless system or the second wireless system, thereby reducing the interference between the first wireless system and the second wireless system. Wherein, the two wireless systems do not need to share a tuning circuit system, but each wireless system is equipped with a tuning circuit system, and the working frequency of the system is adjusted through the tuning circuit system configured by itself, so as to reduce the frequency of the first wireless system. and the purpose of interference between the second wireless system.
另外，该无线终端并不仅仅限于包括两个无线系统，只是目前实际使用中典型的是包括两个无线系统，对于包括多个无线系统，本发明也同样能够实现，可以让调谐电路系统控制多个无线系统，或者增加调谐电路系统的数量以满足控制多个无线系统的需要，总之，不管如何实现，其实现方法皆如本发明实施例提供的降低无线干扰的方法，在这里不再赘述。In addition, the wireless terminal is not limited to include two wireless systems, but typically includes two wireless systems in actual use at present. For including multiple wireless systems, the present invention can also be realized, allowing the tuning circuit system to control multiple wireless systems, or increase the number of tuned circuit systems to meet the needs of controlling multiple wireless systems.
