| Abstract: | In this paper, the authors introduce a detection scheme for adaptive suppression of multiuser interference (MAI) and multipath distortion(MPD) in multipath CDMA channels. The authors provide an adaptive blind multiuser detecting and optimum combining implementation for the two parts of the proposed receiver, based on the least mean square(LMS) algorithm and an adaptive vector tracing algorithm respectively. Finally, the feasibility of the above model and algorithms are proved by the numerical results provided by computer simulation. |
