Abstract

En 中文

This paper presents an adaptive beamforming technique based on the eigen-space method for computing the optimal weight vector that 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 technique rather enhances the performance as the angle spread increases. It is also confirmed in this paper that performance of the proposed technique is almost identical to that of which has been obtained through the exact solution of the eigen-space method.
