Abstract

It is difficult for the adaptive array to reduce interference signals efficiently from the received signals when the interference signals and desired signal are closely located. This is a serious problem for a spatial division multiple access (SDMA) system using the multibeam adaptive array as a multiuser detector. We propose a space domain multistage interference canceller (SD-MIC) for the SDMA. Its performance is evaluated in frame error rate (FER) by computer simulations, considering uplink environment in the Japanese personal handy-phone system (PHS). The results show the remarkable improvement in high spatial correlation situations
