Abstract

CDMA system performance can be enhanced by interference management techniques. We consider the uplink of a CDMA system that employs two such techniques: temporal multiuser detection and spatial antenna array beamforming. Recently, temporal-spatial MMSE type receivers with several different criteria have been proposed for a static channel. In this work, we consider such MMSE filters assuming a multiple time-scale fading 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 employs an MMSE multiuser detector at the output of each array element (temporal MMSE filter) followed by an MRC (spatial matched filter).
