Abstract
This paper is concerned with the investigation of a MIMO-CDMA communication system which is based on the concept of spatiotemporal array (STAR) manifold for handling multipath fading channels. Firstly a MIMO frequency selective channel is modelled as a function of both transmitter's and receiver's antenna-array manifold vectors. Then, assuming knowledge of the channel parameters of the desired user, two linear receivers are proposed. The proposed receivers are `near-far' resistant and expressed in terms of the STAR manifold vector of the desired user. The investigation is supported by computer simulation studies where the performance of the proposed receivers is compared to the performance of conventional MMSE and RAKE receivers which have been also extended in order to be expressed in terms of the STAR manifold vectors.
