| 摘 要： | 针对DS/CDMA系统中多址干扰及远近效应。提出了一种选通并行部分干扰抵消(SPPIC)算法,利用匹配滤波器输出的判决统计对多址干扰进行选通部分抵消,有效地减小判决统计量的偏差,以提高系统性能。给出了选通并行部分干扰抵消检测器的非相干实现结构,通过仿真实验证明该算法的有效性。

| Abstract: | The multiuser detection technique is used to remove the Multiple Access Interference(MAI) and resist near-far effect in the DS/CDMA system.Selective partial parallel interference cancellation(SPPIC) algorithm is presented.In the proposed interference cancellation algorithm,with different coefficients in every stage,reduces the estimation bias of interference and cancels the MAI according to the statistics of its matched filter(MF) output.The non-coherent approach and simulation results of the proposed SPPIC detector also be presented,the simulation results show that the interference cancellation algorithm is efficient. |
