具体实施方式Detailed ways
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
在后续的描述中，使用用于表示元件的诸如“模块”、“部件”或“单元”的后缀仅为了有利于本发明的说明，其本身没有特有的意义。因此，“模块”、“部件”或“单元”可以混合地使用。In the following description, use of suffixes such as 'module', 'part' or 'unit' for denoting elements is only to facilitate description of the present invention and has no specific meaning by itself. Therefore, 'module', 'part' or 'unit' may be used in combination.
正如上述技术背景技术中所述，传统的对信号进行放大的信号处理装置在将至少一种频率的基带信号进行处理得到放大信号的过程中，存在功放效率低的问题。究其原因，现有技术中信号处理装置先对基带信号进行分解，得到分解信号，然后通过双频功率放大器输出放大的模拟信号，在保证对基带信号的振幅和/或相位进行改变得到分解信号的过程中，要么是在为了实现对于基带信号的振幅和/或相位的改变量精准控制，导致器件复杂度过高；要么是器件复杂度不高，但是对于基带信号的振幅和/或相位的该变量的精准度不高，上述情况均会造成进入信号处理装置的双频段功率放大器的合成模拟信号的参数不匹配，存在功放效率低的问题。As mentioned above in the technical background, the conventional signal processing device for amplifying signals has the problem of low power amplifier efficiency in the process of processing baseband signals of at least one frequency to obtain amplified signals. The reason is that in the prior art, the signal processing device first decomposes the baseband signal to obtain the decomposed signal, and then outputs the amplified analog signal through the dual-frequency power amplifier, and then changes the amplitude and/or phase of the baseband signal to obtain the decomposed signal In the process, either in order to achieve precise control of the amplitude and/or phase of the baseband signal, the device complexity is too high; or the device complexity is not high, but for the amplitude and/or phase of the baseband signal The precision of this variable is not high, and the above-mentioned situation will cause the parameter mismatch of the synthetic analog signal entering the dual-band power amplifier of the signal processing device, and there is a problem of low power amplifier efficiency.
针对上述技术问题，本发明实施例提供了如下技术方案，旨在实现一功放效率高的信号处理装置。In view of the above technical problems, embodiments of the present invention provide the following technical solutions, aiming at realizing a signal processing device with high power amplification efficiency.

Components cooperate to execute. Some or all of the physical components may be implemented as software executed by a processor, such as a central processing unit, digital signal processor, or microprocessor, or as hardware, or as an integrated circuit, such as an application-specific integrated circuit . Such software may be distributed on computer readable media, which may include computer storage media (or non-transitory media) and communication media (or transitory media). As known to those of ordinary skill in the art, the term computer storage media includes both volatile and nonvolatile media implemented in any method or technology for storage of information, such as computer readable instructions, data structures, program modules, or other data. permanent, removable and non-removable media. Computer storage media includes, but is not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disk (DVD) or other optical disk storage, magnetic cartridges, tape, magnetic disk storage or other magnetic storage devices, or can Any other medium used to store desired information and which can be accessed by a computer. In addition, as is well known to those of ordinary skill in the art, communication media typically embodies computer readable instructions, data structures, program modules, or other data in a modulated data signal such as a carrier wave or other transport mechanism, and may include any information delivery media .
以上参照附图说明了本发明的优选实施例，并非因此局限本发明的权利范围。本领域技术人员不脱离本发明的范围和实质内所作的任何修改、等同替换和改进，均应在本发明的权利范围之内。The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, and the scope of rights of the present invention is not limited thereto. Any modifications, equivalent replacements and improvements made by those skilled in the art without departing from the scope and essence of the present invention shall fall within the scope of rights of the present invention.
