MODELING AND EVALUATION OF A SIMPLE ADAPTIVE ANTENNA ARRAY FOR A WCDMA MOBILE COMMUNICATION.

ABSTRACT

This thesis presents the uniform Linear Array model of a simple adaptive   antenna array based on signal-to-interference plus noise ratio (SINR) maximization.

The SINR was investigated for a conventional narrow band beam former by varying the number of antenna array elements and number of interfering signals or users. The results were compared with that of omni-directional antenna. The graph obtained showed significant improvement in SINR as the number of antenna elements increases in the presence of large interferers for odd numbered array.
