In this paper, we combine Spatial Multiplexing with a Multi-Carrier Code Division Multiplex Access (MC-CDMA) system associated to a Turbo Coding (TC) scheme. MC-CDMA is likely to be a very promising access technique for future wireless communication systems. In fact, MC-CDMA exploits the advantages of both multi-carrier modulation and Code Division Multiple Access (CDMA) technique. On the other hand, the capacity of multi-antenna system can linearly increase with the minimum of transmit and receive antennas using Spatial Multiplexing. We study the concatenation of Multiple Input Multiple Output (MIMO) systems for Nt transmit and Nr receive antennas and MC-CDMA with a TC scheme. Simulation results are provided for different loads in order to demonstrate the efficiency of spatial multiplexing combined with turbo channel coding scheme for a multi-user system based on MC-CDMA for both uncorrelated and correlated antenna systems.
