  Abstract

In this paper, we have presented a new adaptive beamforming technique based on eigen-space method. The proposed beamforming technique utilizes the primary and secondary eigenvectors to form the beamforming weight vector. They are computed using the Lagrange algorithm. From various computer simulations, it is confirmed that as the angle spread increases from the center angle of arrival, the performance of a typical beamforming technique using only a single eigenvector degrades rapidly. But, the performance of the proposed technique improves on the contrary.
