Comparison of antenna array algorithms for CDMA mobile communications systems

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.
