Abstract :
Interleave-division multiple access (IDMA) has recently been introduced in relay systems in order to exploit diversity gain. Combining with delay-diversity (DD), the relay scheme based on IDMA can support multiple users. In this paper, we extend the DD-IDMA relay scheme to MIMO relay networks employing spatial multiplexing. We also develop a symbol-by-symbol iterative detection method at the destination for the system. The performance of the MIMO relay system is assessed through simulation results.
