Spatial multiplexed coded MC-CDMA with iterative receiver

In this paper, the combination of spatial multiplexing with coded multi-carrier code division multiplex access (MC-CDMA) for a multiple input multiple output (MIMO) Rayleigh fading multipath channel is considered. A practical receiver structure performing the iteratively MIMO detection, multi-user despreading and channel decoding is presented. The MIMO detector, employing a linear minimum mean square error (MMSE) parallel soft interference canceller (PSIC) equalizer, allows to cope with the co-antenna interference (CAI). Simulation results show the efficiency of the iterative receiver for spatial multiplexed coded MC-CDMA that brings spatial diversity, increasing data rate, and multi-user flexibility.
