CO-CHANNEL DUAL POLARIZED MICROWAVE DEVICE AND RECEIVING METHOD FOR RECEIVING SIGNAL

摘要

Embodiments of the present invention disclose a co-channel dual polarized microwave device and a method for receiving a receive signal. Frame synchronization is performed on a first receive signal processed by cross polarization interference cancellation and phase noise immunization is performed on the first receive signal processed by frame synchronization. Frame synchronization is performed on a second receive signal not processed by cross polarization interference cancellation and phase noise immunization is performed on the second receive signal processed by frame synchronization. The first receive signal processed by phase noise immunization and the second receive signal processed by phase noise immunization are selectively received according to a frame synchronization state signal and a signal quality signal. Delay alignment is performed on a selectively received signal according to the frame synchronization state signal to implement lossless switching in a selective receiving process. If a cross polarization interference cancellation error occurs due to a microwave device fault, a microwave device selectively receives the receive signal not processed by cross polarization interference cancellation and performs delay alignment, thereby implementing lossless switching in the selective receiving process.
