Abstract: A method includes: The receive end receives 2N channels of signals through N first antennas, where the 2N channels of signals are respectively from N second antennas of the transmit end. When transmission performance of any one of the 2N channels of signals is less than a first threshold, the receive end respectively receives, from two second antennas, two channels of signals whose polarization directions are orthogonal. When transmission performance of the two channels of signals is both greater than a second threshold, the receive end receives the 2N channels of signals through the N first antennas.

Abstract: A microwave transmission apparatus is provided. A multiplexing unit generates multiplexed data based on a service clock rate. An interface unit writes and reads the multiplexed data at the service clock rate and a read clock rate respectively. An encoding and mapping unit performs encoding and mapping on the multiplexed data using a symbol clock rate to generate symbol data, and sends the symbol data to up conversion units. A clock tracking unit generates the symbol clock according to the system clock, and performs frequency division on the symbol clock to acquire the read clock. A stream control unit adjusts the service clock rate according to a water line error generated by the interface unit, so that the service clock rate is equal to the read clock rate. As a frequency and a phase of the system clock are fixed, even ACM switching occurs, the system clock is stably transferred.
