  Abstract

This paper proposed the method of finding optimal weight vectors for enhancing the performance of an adaptive array antenna system by adopting a novel beam-forming algorithm in CDMA (code division multiple access) channel This algorithm is a linearized power method, based on power method, with the total computational load, O(4N) Where, N denotes the number of antenna elements The performance of the proposed algorithm is shown in terms of SER (symbol error rates), allowable capacity, and the convergence characteristic in IS2000 1X CDMA channel As a result of simulations, the adaptive array antenna system allows 6-10 times more users than the conventional one in a cell of a base station Furthermore, the proposed algorithm shows superior performance to the conventional one regarding symbol error rates, converging characteristics, and computational load.
