Abstract :
A trellis-based multiuser detection algorithm called bias compensated matched filter decision feedback sequence estimation (BCMFDFSE) is considered for DS-CDMA systems under frequency-selective fading environments. The development of the wideband DS-CDMA standard demands the consideration of frequency selectivity in designing systems. In this paper, we propose BCMFDFSE as a possible receiver structure that has nice performance/complexity tradeoffs. We compare BCMFDFSE with other algorithms such as successive interference cancellation (SIC) and parallel interference cancellation (PIC)
