Abstract
In this paper, novel wavelet packet spread spectrum (WPSS) communication system based on the complex radial basis function (CRBF) network equalizers is studied for multipath fading channels. The complex radial basis function network equalizers technique is adopted to suppress Inter-Symbol Interference (ISI) caused by multipath fading channels and reduce the symbol error rate (SER). The system performance is investigated in multipath fading channels. The theoretical analysis and simulation results show that the proposed CRBF channel equalizer structure which uses least mean square (LMS) algorithm to obtain the optimized equalizer weights offers both fast convergence and low value of the mean square error; the proposed CRBF-WPSS system has a superior SER performance to that of the conventional CRBF-OFDM-SS (spreading spectrum) system, and the proposed CRBF-WPSS system outperforms the WPSS system base on zero-forcing equalizers for multipath fading channels.
