A linear complexity detection method and iterative equalization for coded MIMO systems

We consider the problem of achieving high data rates for uplink transmission on multi-input, multi-output (MIMO) channels. We propose a soft decision space-time detection scheme of linear complexity in a turbo-coded architecture with a new form of iterative processing. Simulation results illustrate that the coded MIMO system is within 1.5 dB of the Shannon capacity limit on uncorrelated flat Rayleigh fading MIMO channels, where the receiver only possesses channel state information.
