The paper proposes a novel turbo equalization method, called SC/simplified-MMSE (S-MMSE), for multiple-input multiple-output (MIMO) channel signal transmission. Turbo equalization is an iterative equalization and decoding process. Our method, which deals with residual inter sub stream interference as their average over a frame, achieves excellent error performance at small computational cost. We evaluate our method by link-level and system-level simulations. A complexity comparison is also presented.
