摘　　要：同时考虑系统性能和运算量,将多步联合检测和迭代多用户检测技术结合起来,提出了多步迭代多用户检测技术。相对于单纯的MSJD,系统性能将大大提高;相对于单纯的迭代多用户检测,运算量将大大减少。Considering system performance and compute complexity,based on multi-step joint detection and iterative multi-user detection, multi-step iterative multi-user detection technology is brought forth, which will improve system performance comparing with MSJD and reduce complexity comparing with iterative MUD.

关 键 词：同步CDMA系统 迭代多用户检测 多步联合检测 多步迭代多用户检测
