A new and improved turbo processing multi-input multi-output (MIMO) system using a nonlinear minimum mean square error (MMSE) detector is proposed. Based on the nonlinear mean square (MS) estimation, the a posteriori information of a soft-input soft-output (SISO) decoder is fed back to the MMSE detector instead of the extrinsic information. Unlike a MAP (maximum a posteriori) detector, the MMSE detector shows no error propagation caused from using the a posteriori as an a priori information… CONTINUE READING
