Receiver spatial-temporal signal processing for broadband wireless systems

This chapter reviews the basic techniques of adaptive spatial and temporal processing, which have been shown to yield substantial improvements in capacity and performance of wireless systems. After a review of appropriate transmission channel models, we introduce the elements of linear and nonlinear space-time processing, and outline their capabilities for combating interference and multipath. We then describe some applications and discuss adaptation issues. While many of the applications focus on receiver space-time processing, there is growing interest and promise in transmitter space-time processing as well.
