Abstract

We consider the impact of multiple access interference (MAI) on noncoherent code tracking loops (in conventional CDMA matched filter detectors) and a novel interference canceller is proposed in order to eliminate the steady-state tracking error, reduce the RMS tracking jitter and realize fast and reliable synchronization. We introduce the idea of multiuser detection such as successive interference cancellation. Simulation results demonstrate the loop exhibits a higher performance than that of the conventional code tracking loop
