1. A microwave transmission method, comprising:
receiving, by a receive end, 2N channels of signals through N first antennas, wherein the 2N channels of signals are respectively from N second antennas of a transmit end, each first antenna of the N first antennas receives the 2N channels of signals, each second antenna of the N second antennas sends two channels of signals, and N is an integer greater than or equal to 2;
when transmission performance of any one of the 2N channels of signals is less than a first threshold, respectively receiving, by the receive end, two channels of signals from two of the second antennas, wherein polarization directions of the two channels of signals are orthogonal; and
when transmission performance of the two channels of signals is both greater than a second threshold, receiving, by the receive end, the 2N channels of signals through the N first antennas,
wherein the transmission performance comprises one or more of the following: an equivalent antenna distance or a multipath notch depth, wherein the equivalent antenna distance is a ratio of an actual antenna distance to a Rayleigh antenna distance, the actual antenna distance is a physical distance between two of the N first antennas of the receive end, and the multipath notch depth is used to indicate a multipath notch degradation degree.
