Dual polarization microwave device in the same channel and receiving method for receiving the receipt signal

Abstract

The present invention discloses a dual polarization microwave device in the same channel and a receiving method for receiving the receipt signal, being characterized by: performing frame synchronization processing to the first receipt signal after the cross polarization interference cancellation; performing phase noise immunization processing to the first receipt signal after frame synchronization processing; performing frame synchronization processing to the second receipt signal which is not processed by the cross polarization interference cancellation; performing the phase noise immunization processing to the second receipt signal after the frame synchronization processing; selectively receiving the first receipt signal and the second receipt signal after the phase noise immunization processing according to the frame synchronization state signal and teh signal quality signal; performing delay alignment for the selectively received signals according to the frame synchronization state signal so as to realize the lossless switching of the selectively receiving process. If a microwave device failure causes a cross polarization interference cancellation error, the microwave device selectively receives the receipt signal which is not processed by the cross polarization interference cancellation and performs the delay alignment processing so as to realize the lossless switching of the selectively receiving process.

Description

technical field [0001] The invention relates to the field of wireless technology, in particular to a co-channel dual-polarization microwave device and a receiving signal receiving method. Background technique [0002] Microwave technology transmits data directly through space without laying optical fibers or cables. It has obvious engineering advantages in cities, remote areas or special areas such as rivers. Microwave technology is convenient for networking, flexible in use, and short in service opening time; With the development of microwave technology, the cost of microwave equipment is gradually reduced. Therefore, microwave technology is used more and more widely. [0003] The co-channel dual polarization (Co-Channel Dual Polarization, CCDP) transmission technology can realize the simultaneous transmission of horizontal polarization (Horizontal Polarization, H) and vertical polarization (Vertical Polarization, V) two orthogonal Polarized waves double the capacity of si...
