ABSTRACT:
Improvement of interference canceling efficiency and communication system capacity due to the use of the optimal decision function in adaptation of the adaptive antenna array weight factors. An adaptive antenna array pattern forming algorithm is used. The weight vector is determined from the position of the decision function maximum. The proposed decision function is based on estimation of signal to interference plus noise ratio (SINR) at the adaptive antenna array output and is no singular even without noise and interference.
