Optimal detection based on adaptive array antenna in spatial and temporal domains

Abstract

This paper derives a generalized matched filter in spatial and temporal domains using an adaptive array antenna. The matched filter provides the optimal transfer function so as to maximize SINR (signal to interference-plus-noise ratio) in the array output. Moreover, if the generalized matched filter is followed by maximum likelihood sequence estimator in order to utilize memory in the channel, a generalized optimal receiver based on array antenna can be realized.<>
