Abstract

The aim of this paper is to employ parallel rake receivers to decode the orthogonality-inherent space-time spreading and to overcome the signal time dispersion in the MIMO-CDMA wireless systems. To decrease the inter-symbol interference (ISI) caused by signal propagation delay due to the multipath effect, we propose a reconstruct and suppress mechanism to reduce the influence. Our system with maximum ratio combining (MRC) and low complexity maximum likelihood (ML) detector can achieve a better performance in non-quasi static channel. Simulation results show that the proposed MPI suppression mechanism can lower the error floor significantly than conventional MIMO-CDMA with space-time block code (STBC) in multipath environment over fast fading channel.
