Evaluation of the Interference and Noise Suppression Capability of Uniform Linear Array Adaptive Beamforming Antenna

Abstract—This paper evaluates the interference and noise suppression capability of uniform linear array adaptive beamforming antenna, at base stations of WCDMA mobile communication system. The signal-to-interference and noise ratio (SINR) was the performance index used for the evaluation and analysis. SINR was investigated for a conventional narrow band beam former by varying the number of antenna array elements, the inter-element spacing 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.

Index Terms—Adaptive antenna arrays, uniform linear arrays, beamforming, interference suppression and noise reduction capability.
