This paper assesses the performance of a multiuser detection DS/CDMA receiver based on
a hybrid scheme of successive interference cancellation (SIC) and parallel interference …

We study the improvement technique for multistage parallel interference cancellation (PIC)
DS-CDMA multiuser receivers, which cancel only a fraction of the estimated multiple access …

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 …

Non-orthogonal multiple access (NOMA) is one innovative technology that provides low
latency, high system capacity, high spectrum efficiency, and massive connectivity to solve …

We propose a signal processing technique, based on the estimate-maximize algorithm, in
order to perform multiuser code-division multiple-access (CDMA) detection. This algorithm …
