ABSTRACT:
A signal processing method and apparatus for obtaining a diversity gain in the communication system equipping the antenna array when a background noise is a space white noise or a non white noise is disclosed. The signal processing method and apparatus includes steps and functions of calculating a covariance matrix, estimating at least two time invariance vectors by performing an eigen-disintegration operation, estimating a channel vector and outputting a beam-forming vector. The present invention can improve the performance of the antenna array by using at least two time invariance vectors and it also increase a communication quality and quantity of the communication system, if the present invention is implemented to the wireless communication system.
