Abstract :
This paper proposes a new blind adaptive algorithm for computing the weight vector of an antenna array system that provides the beam pattern having its maximum gain along the direction of the mobile target signal source in the presence of strong interference. The proposed algorithm provides a suboptimal weight vector maximizing the SINR (signal to interference plus noise ratio) with a linear computational load. Based on the analysis obtained from various simulations, it is observed that the proposed algorithm is suitable for practical IMT2000 mobile communication environments
