Adaptive antenna array utilizing the conjugate gradient method for compensation of multipath fading in a land mobile communication

The problem of designing an adaptive antenna array as a countermeasure to the multipath fading which occurs in land mobile communications is addressed. In order to approach the optimal weights of the antenna elements on a real-time basis, the conjugate gradient method (CGM) is applied to some practical procedures which have been contrived as realizable alternatives. The performance of the proposed technique is compared to that of the conventional recursive least square (RLS; Kalman) algorithm in terms of bit-error-rate (BER) and required computation time
