This paper presents a novel adaptive beamforming algorithm for a smart antenna base station system (SA BTS). The new technique is based on the eigen-space method for computing the optimal weight vector which does not degrade the receiving performance even in wide angle-spread circumstances. By exploiting the diversity gain, which is available in the signal environments of the wide angle-spread, the proposed method rather enhances the performance as the angular spread of the desired signal increases nearly up to ±20°-30° from the center of arrival angle. The proposed technique is applied to IS2000 1X signal environment to show its excellent performance compared to a typical beamforming method which considerably degrades the receiving performance of the SA BTS as the angular spread of desired signal increases.
