Hybrid precoding method based on electric power inspection communication system

The invention relates to a hybrid precoding method based on an electric power inspection communication system. The electric power inspection communication system adopts a narrowband millimeter wave large-scale multiple-input multiple-output system, and comprises a transmitting end located on an unmanned aerial vehicle and a receiving end of a wireless network, wherein the transmitting end is provided with a hybrid precoder, the receiving end is provided with a beam combiner, an analog precoder is provided with a radio frequency chain and a uniform planar antenna array, the radio frequency chain is connected with an antenna part of the uniform planar antenna array, a one-bit phase shifter is adopted as a phase shifter at the joint, and the quantization precision of the corresponding phase shifter is 1 bit. Compared with the prior art, the hybrid precoding method has the advantages of reducing power consumption, improving the communication energy efficiency of the unmanned aerial vehicle, reducing the complexit
