An TSK Fuzzy Approach to Channel Estimation for MIMO-OFDM Systems

This paper proposes an TSK fuzzy approach to channel estimation for multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems. The information of dispersive fading channel is described by using TSK fuzzy model, which is updated by using the decision feedback symbol or the scattered pilot symbol. Space-time block coding (STBC) is used to get the diversity gain. Computer simulation demonstrates that the proposed algorithm has the same word error rate (WER) performance compare to the minimum mean-square-error (MMSE) method. Because it is without the computation of inverse matrix in MMSE, the proposed algorithm has a low burden of computation
