摘要 文章主要分析了最小均方误差 (MMSE)自适应检测器应用于CDMA系统的性能 ,建立了系统信号模型 ,给出了计算误码率的公式。并且将MMSE自适应检测器的性能与最佳单用户检测性能进行了比较 ,得出了MMSE自适应检测器性能要优于最佳单用户检测的结论。 The performance of minimum mean square error (MMSE) adaptive detector applied in CDMA system is analyzed in this paper. The signal model is set up, and the relevant bit error rate formulas are given. The system performance of MMSE adaptive detector is compared with that of optimal single user. It is concluded that the performance of MMSE adaptive detector is better than that of optimal single user. Finally the computer simulation result is given.
