Spatial multiplexing applied to turbo coded multicarrier CDMA

We combine spatial multiplexing with a multi-carrier code division multiple 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 the multi-carrier modulation and code division multiple access (CDMA) technique. On the other hand, the capacity of a 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 N_t transmit and N_r 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 the turbo channel coding scheme for a multiuser system based on MC-CDMA for both uncorrelated and correlated antenna systems.
