Abstract :
Wideband DS-CDMA has gained a lot of attention for the third generation wireless systems (UMTS and IMT-2000). On the other hand, multiuser detection has been under intense research since the formulation of optimum multiuser detector by Verdu in 1986. For the third generation wireless systems, several wideband CDMA schemes with multiuser detection have been proposed. This paper presents an overview of developments in the field of multiuser detection for DS-CDMA. Finally, possible future research directions are suggested
