Abstract

Summary form only given. Various linear and nonlinear algorithms for adaptive antenna arrays in code division multiple access (CDMA) mobile communication systems are investigated. The computer-simulated system model incorporates QPSK-CDMA modulation, demodulation, diversity channels and adaptive array structures. Diversity channels are time-varying and have frequency-selective fading characteristics. Simulation results show that the optimal technique in terms of performance and computational complexity is based on a recurrent neural network (RNN) structure
