| 摘 要： | 研究一种基于维纳滤波器的抗多址干扰(multiple access interfere,MAI)盲检测方法——辅助矢量滤波器(auxiliary vector filter,AVF),该方法不仅能够有效去除CDMA(code division multiple access)系统中的多址干扰,而且具有无需增加模块、无需求逆矩阵、可运用于下行链路、便于盲实现、计算复杂度低等优点.仿真结果表明:对于CDMA系统,在不同的干扰强度和不同的干扰用户数两种环境下,辅助矢量滤波器抗多址干扰的性能远远优于传统相关滤波器.

| Abstract: | The blind detection method(auxiliary vector filter) of anti-MAI(multiple access interfere),based on Wiener filter,is studied in this paper.The method not only can cancel the MAI,but also needs no more module,and no inversion of matrix.It can be blindly applied to the forward(base-to-mobile) and its complexity is very low.The simulation results indicate that when the interference is different or the number of interfere users is different in the CDMA system,the performance of the auxiliary vector filter is mu... |
