Adaptive multiuser detector for asynchronous DS-CDMA in Rayleigh fading

This paper deals with multiple access interference cancellation for an asynchronous direct sequence code-division multiple-access (DS-CDMA) system in the presence of channel fading. We propose an adaptive detector for signal decorrelation during every bit period by having the knowledge of signature waveforms. The performance of this detector is compared to other detectors under Gaussian channel noise and fading condition.
