Low complexity iterative receiver for linear precoded MIMO systems

Abstract : In a Multiple Input Multiple Output (MIMO) context, we present, in this paper, a Space-Time Bit Interleaved Coded Modulation (STBICM) system combined with a spacetime spreader called linear precoding. We propose a practical low-complexity receiver structure performing iteratively space-time detection and channel decoding. The novelty lies in the linearity of the space-time detector which consists of an MMSE MIMO PSIC equalizer and a linear deprecoder. Spectral efficiency and diversity can easily be tuned while keeping feasible receiver. In the case of independent flat Rayleigh fading, simulation results show that such system exploits both spatial diversity and capacity provided by the multi antenna system.
