Performance evaluation for conventional and MMSE multiuser detection algorithms in imperfect reception conditions

This paper presents three multiuser detectors structures: the conventional detector, the MMSE and the adaptive detector. The error probability performances are evaluated and compared one another, as functions of signal to noise ratio, for a system with four users, and different intercorrelation coefficients and users amplitudes. Based on those simulations, a number of conclusions are drawn with respect to the effects of the intercorrelation between users or unequal amplitudes on the detectors performances.
