Abstract CDMA system perjbrmance can be enhanced by interference management techniques. We consider the uplink oja CDMA system that employs two such techniques: temporal multiuser detection and spatial antenna array heamjhrming. Recently, temporal-spatial MMSE vpe receivers with several diflerent criteria have been proposedjor a static channel. In this work, we consider such MMSEjlter.7 assuming a multiple time-scale jading channel model. It is shown that under the given channel conditions and system assumptions, three recently proposed MMSE type receivers; the unconstrained optimum MMSE detector. the constrained optimum MMSE detector and the cascaded temporal-spatial MMSE detector: are identical and the resulting combined receiver emplqa an MMSE multiuser detector at the output of each arrav element (temporal MMSEfilter) jdlowed by an MRC (spalial ma tchedjlter). 1.
