Abstract

This paper discusses tolerances of impairment factors in a proposed co-channel interference canceller that is applied to a point-to-point (P-P) wireless system using quasi-millimeter frequency band (22 GHz and 26 GHz). The interference canceller can double a data rate of the system using two P-P wireless links. which are deployed in parallel. The two links use the same frequency band and the same polarization. We analytically estimate the proposed canceller performance when a replica of an interfering signal has static phase and amplitude errors. The calculation results show that the proposed canceller could improve an error rate performance in the presence of the errors.
