Fast Multi-user Detector for a Time-varying CDMA System
Das, Suman; Cavallaro, Joseph R.; Aazhang, Behnaam
This paper investigates methods to reduce the amount of computation needed to detect information bits using a linear detector for a CDMA system. We show windowing technique coupled with pipelining can reduce the amount of computation without significantly sacrificing the performance of linear feedback detector. We also describe efficient techniques to adapt to a dynamic system where the system parameters vary due to the change in delays associated with individual users.
