| 摘 要： | 用模块化的方法描述了 ＳＩＣ、ＭＳＳＩＣ、ＰＩＣ和ＰＳＩＣ干扰抵消多用户检测算法，给出算法的实现结构图，并且在渐近有效性、抗远近效应、系统容量和实现复杂度诸方面进行了性能比较分析。分析表明需要进行功率排序的ＭＳＳＩＣ、ＰＳＩＣ和ＳＩＣ算法比ＰＩＣ算法具有更好的抗远近效应的性能，ＭＳＳＩＣ和 ＰＳＩＣ算法在渐近有效性和系统容量方面要显著强于ＳＩＣ和ＰＩＣ算法。

| Abstract: | This paper is to present Interference Cancellation of SIC, MSSIC, PLC and PSIC for DS/ CDMA communications based on ICU module. The algorithms are compared and analyzed in this paper. The simulations indicate that MSSIC, PSIC and PLC have better Near - Far resistance than PlC, while MSSJC and PSJC outperform SIC and PLC in the asymptotic multi - user efficiency and number of users. |
