| Abstract(in English) | It is one of the most important issues for Code Division Multiple Access mobile receivers how to overcome the performance degradation caused by interference noise. Interference canceller and decision feedback demodulator with LMSE have been pursued so far. To cope with short time phase change in the interference noise, a frame by frame inference function is considered. The inference principle is based on the despread ulternate component taken at the matched filter and adding of such an additional noise that makes the noise orthogonal. The estimation principle and the application example to a system using a complementary spreading code are shown. As a consequence, noise estimation that does not depend on the received noise power is presented. |
