Simulation and Evaluation of a Simple Adaptive Antenna Array for a WCDMA Mobile Communication

This paper presents a uniform Linear Array model of a simple adaptive antenna array based on Signal-to-Interference and Noise Ratio (SINR) maximization. The SINR using the adaptive antenna array was investigated for a conventional narrowband beam former by varying the number of antenna array elements and number of interfering signals or users. The results obtained were compared with that of omni-directional antenna. The graph obtained from the results showed significant improvement in SINR as the number of antenna elements increases in the presence of large interferers for odd numbered array.
