ADAPTIVE ARRAY BEAMFORMING BASED ON AN EFFICIENT TECHNIQUE

This paper presents a new processing technique for adaptive array beam forming, We first properly decompose the optimal weight vector associa ted with the original array beamformer into several adaptive weight su bvectors. An adaptive algorithm based on the conventional RLS algorith m is derived to update the weight subvectors. The required computation al complexity is also evaluated for the proposed technique. The conver gence rate of the proposed technique is mainly affected by the size of the largest weight subvector. Faster convergence speed and less array sensitivity to the pointing errors can be achieved by using the propo sed technique, Several simulation results are included for illustratio n and comparison.
