Abstract
Multiple access interference (MAI) is a key problem in DS-CDMA. Both multiuser detection method and antenna array technique have been introduced to reduce the effect of MAI respectively. In this paper, combining wavelet networks with a space-time filter, we propose a novel multiuser detector (MUD). The complexity of the MUD only depends on that of wavelet networks. With numerical simulations and performance analysis, it is shown that the MUD precedes the conventional Rake receiver and the space-time matched filter in eliminating MAI and near-far resistance.
