Abstract
The capacity and performance of code division multiple access (CDMA) systems are limited by multiple access interference (MAI) and ”near-far” problem. Space-time multiuer detection combined with adaptive wavelet networks over frequency selective fading multipath channels is proposed in this paper. The structure of the multiuser detector is simple and its computational complexity mostly lies on that of wavelets networks. With numerical simulations and performance analysis, it is shown that the proposed detector can converge at the steady state rapidly and offer significant performance improvement over the space-time matched filtering detector, the conventional RAKE receiver and matched filter detector only at the time domain. Therefore, it can suppress the MAI and solve the ”near-far” problem effectively.
