Signal processing method utilizing an eigenvector corresponding to the maximum eigenvalue of an autocorrelation matrix of received signals for an antenna array system

摘要

This invention provides a signal processing method for enhancing the communication quality and increasing the communication capacity by reducing the effects of interference and noises with the nice beam pattern. The signal processing method provides a beam pattern by computing an eigenvector corresponding to the maximum eigenvalue of an autocorrelation matrix of received signals in an antenna array system. The inventive signal processing method introduces a simplified computational technique for generating a nice beam pattern having its maximum gain along the direction of the wanted signal and maintaining the gain toward the direction of the interfering signals in as low a level as possible.
