摘要：
In this paper, we propose a minimum mean square error (MMSE) sorted QR decomposition (SQRD) based soft-input soft-output (SISO) detection algorithm for coded multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) systems. The proposed detection is derived from the SISO MMSE detection, which is a popular detection strategy for iterative receivers. For each transmitted symbol in the proposed detection, a soft successive interference cancellation (SIC) is performed based on a posteriori probabilities of past detected symbols. Simulation results show that the proposed detection, while needing less computational efforts, achieves significant performance gain compared with the SISO MMSE detection.
