Low-Complexity Map Channel Estimation for Mobile MIMO-OFDM Systems

Abstract-- This paper presents a reduced-complexity maximum a posteriori probability (MAP) channel estimator with iterative data detection for orthogonal frequency division multiplexing (OFDM) systems over mobile multiple-input multipleoutput channels. The optimal MAP estimator needs to invert an NNT
