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 asymptotic performance of the LR detectors is compared with that of the traditional square law detector.

Finally, a successive interference cancellation (SIC) scheme is proposed combined with minimum mean square error (MMSE) detection. Its performance is superior to simple SIC or MMSE detector.
