At present, multiple input multiple output has become one of the key technologies of the fifth generation mobile communication system due to its advantages of high spectral efficiency, high data transmission efficiency, high reliability, high coverage rate and low delay.

At the receiving end, the purpose of diversity is achieved by configuring multiple receiving antennas. According to the transmission structure, the classic MIMO technology used in 5G communication is mainly divided into two categories: spatial multiplexing and spatial diversity. The basic principle of spatial multiplexing technology is to maximize the transmission rate by transmitting different bits of information on different transmit antennas.
