Performance Analysis of CDMA System for MMSE Adaptive Detector

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.
