A robust receiver for multi-user uplink DS-CDMA

This paper presents a robust receiver for uplink direct sequence code-division multiple access (DS-CDMA) systems. The receiver uses low order auto-regressive models to approximate the multi-path fading channel taps, and a post correlation-based uncertain model for estimation purposes.
