Doubling the through-put of a Digital Microwave Radio system by the implementation of a cross-polarization interference cancellation algorithm

Digital Microwave Radio communications is not a new commercial theatre but is an area that is fostering several novel implementations of older ideas. The present application for Digital Microwave Radio is for use in the backhaul of high-speed data and digitized voice and video communications. This single channel implementation operates as a point-to-point radio link on carrier frequencies from 6 to 38 GHz, each operating at data rates of up to 500 Mbps. Faced with limited spectrum but increased demand for doubling of data rates the use of orthogonally polarized channels has been incorporated. By using the same carrier frequency for two channels, simultaneously, while incorporating orthogonal polarization, allows a doubling of data rate yet not increasing the required width of RF spectrum.
