摘要: A new adaptive beamforming procedure is presented. The main contribution of the proposed technique in its simplicity without loss accuracy. computational load about O(2N/sup 2/+6N). It can further be reduced to O(4.5N) by approximating autocovariance matrix with instantaneous signal vector at each snapshot. applied base station a code division multiple access (CDMA) mobile communication system demonstrate performance terms SINR (signal interference+noise ratio), BER (bit-error-rate), and eventually capacity given CDMA cell/sector.
