SINR MAXIMIZING INTERFERENCE CANCELING METHOD FOR WIRELESS COMMUNICATION SYSTEM

摘要

A noise elimination method for maximizing an SINR(Signal to Interference plus Noise Ratio) for a wireless communication system is provided to receive a signal having a small error by considering even interference of other users in downlink of the wireless communication system, thereby realizing better noise elimination performance. A reception signal including an intrinsic code allocated to a user is received. Linear transformation is carried out with an inverse matrix of covariance of white noise and an interference signal source for maximizing an SINR. Noise is eliminated from the reception signal by using the corresponding user's intrinsic code, the inverse matrix of the covariance of the white noise, and the interference signal source.
