Abstract

The conventional CDMA signal detector suffers from MAI (multiaccess interference). Even with perfect power control, MAI always exists and accumulates when the number of users increases, such that the system capacity is limited. Under a wireless mobile channel, the case becomes worse and the detection of the desired CDMA signal, particularly in a fading environment, becomes more difficult. There have been numerous proposals for near-far resistant detectors, adaptive or non-adaptive, most of which assumed an additive white Gaussian noise (AWGN) channel. This paper evaluates the performance of the conventional detector (which uses solely a filter to match to the desired user) and the bootstrap adaptive detector under a slow fading environment. It compares the performance of a conventional detector and a bootstrap adaptive detector with that of a single user detector (no MAI) under a flat Rayleigh fading channel. Simulation and theoretical results show that the bootstrap adaptive detector gives a performance close to the single user detector and it remains near far resistant as it is under an AWGN channel. © 1998 IEEE.
