Abstract :
We investigate iterative detection and decoding, a.k.a. turbo detection, for multiple-input multiple-output (MIMO) transmission. This investigation is based on a low complexity soft output MIMO detector with a priori information feedback. We show that maximum a posteriori performance (without turbo iteration) can be achieved, at a much lower computational cost, by using the proposed soft-output MIMO detector.
