Millimeter wave communication transmission method based on multi-channel technology

The invention belongs to the technical field of millimeter wave communication, and particularly relates to a millimeter wave communication transmission method based on the multi-channel technology. According to the invention, the problems that the millimeter wave wavelength is short, the diffraction capability is poor and the communication link is easy to block are solved through three key technologies of judging the auxiliary signal, the distributed antenna and the channel selection switch. According to the scheme, the main channel and the standby channel are separated in the spatial domain through the distributed antenna, the judgment auxiliary signal is inserted into the data of the transmitting end, the channel quality is obtained through analysis by combining the judgment auxiliary signal on the channel selection switch of the receiving end, and the channel with the good quality is selected through the channel selection switch. The quick recovery of the transmission link after the millimeter wave channel
