摘要: 针对多址干扰与径间干扰严重地影响多用户空时分组码 (STBC) CDMA系统容量的问题,提出了采用基于加权多级非线性并行干扰删除的空时分组码 (基于WNPIC的STBC)多用户 CDMA方案,并从理论上分析和比较了基于 RAKE接收的空时分组码系统和基于加权多级非线性并行干扰删除空时分组码系统的误码率性能 .

Abstract: Aiming at the capacity of multi-user STBC systems dramatically affected by MAI and IPI, the scheme of multi-user CDMAS TBC based on multistage

weighted non-linear PIC (WNPIC) is proposed. And the BER perfo rmances of STBC systems based on both RAKE and multistage WNPIC are analyzed and compared theoretically.
