| 摘 要： | 在DS/CDMA系统中,采用多用户检测技术可以有效地克服多址干扰(MAI,MultipleaccessInterference)及远近效应。本文提出了一种自适应部分干扰抵消(APPIC,AdaptivePartialParallelInterferencecancellation)算法,根据匹配滤波器输出的判决统计对多址干扰进行选通抵消,以提高系统性能。同时本文给出了自适应部分干扰抵消接收机的非相干实现方案,并给出了仿真结果。

| Abstract: | In DS/CDMA system, the multiuser detection technique is used to remove the Multiple Access Interference (MAI) and resist near-far effect. In this paper Adaptive Partial Parallel interference cancellation (APPIC) algorithm is present. In the proposed multiuser receiver, with different coefficients in every stage, cancels the MAI according to the statistics of its matched filter (MF) output. The non-coherent approach and simulation results of the proposed APPIC receiver also be present. |
