Abstract :
In this paper the joint effects of the inter-cell macrodiversity schemes combined with intra-cell spatial multiplexing are investigated for MIMO-OFDM systems. We compare the SINR and throughput performances of cellular Alamouti, cellular cyclic delay diversity (CDD) schemes and pure macrodiversity at the cell edge. Our simulation results indicate that cellular Alamouti scheme outperforms cellular CDD scheme, and the CDD has similar performance as the pure macrodiversity scheme. This result is useful to determine the suitable macrodiversity scheme when spatial multiplexing are implemented at the user terminals.
