Multiuser detection in DS-CDMA systems using POCS algorithm

This paper presents the results obtained by a new multiuser detector based on the Projection Onto Convex Sets (POCS) deconvolution algorithm, in comparison with those obtained by the decorrelating detector, when the channel is affected by the flat Rayleigh fading and gray images are transmitted through the system. All the users transmit their information with the same power, but the spreading codes are correlated. We will investigate the fading effect on the received images and the impact of the cross-correlation of the spreading codes on the quality of the received images. In the end, several conclusions are highlighted, with respect to the level of performance achieved.
