| 摘 要： | 从Turbo编码的同步CDMA系统中多用户检测技术的应用着手，重点研究了多步联合检测技术和迭代多用户检测技术，并在仿真结果的基础上把2种技术结合起来，提出了一种新的检测技术，相对于单纯的MSJD，其系统性能将大大提高，相对于单纯的迭代多用户检测，运算量也将大大减少。

| Abstract: | In the paper,the application of multi-user detection technology for synchronous turbo-coded CDMA is focused on,and two technologies, multi-step joint detection and iterative multi-user detection, are exploited.Based on simulation results,a new technology, combined by MSJD and iterative MUD, is brought forward,which greatly improves system performance compared with MSJD and reduces complexity compared with iterative MUD. |
