Abstract :
In this overview, we review the basic reception 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 current applications and discuss adaptation issues
