It is noted that the minimum mean square error (MMSE) detector often loses phase to lock a desired signal when the desired signal dips into a deep fade.
在实际通信系统中当信号处于深衰落时，最小均方误差(MMSE)检测器经常失去对信号的相位跟踪。

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.
