Abstract A low complexity detection scheme for the MIMO system with distributed transmit antennas is presented. Based on a Sorted CHolesky Decomposition (SCHD), the additive gaussian color noise after match filter is whitened; The detection sequence according to the post signal noise ratio is reordered, and the risk of error propagation is degraded. The whole algorithm only requires one matrix inverse. Simulation results show that the presented algorithm has better performance and lower complexity compared to the existing detection scheme over Rayleigh fading channels.
