Abstract	In this paper, we study low complexity transceiver for double space time transmit diversity (D-STTD) and orthogonal frequency division multiplexing (OFDM) system with antenna shuffling. We utilize a simple antenna shuffling method based on the criterion of minimum mean square error (MMSE). We propose an algorithm to reduce the amount of feedback by exploiting the fact that the channel frequency responses across OFDM subcarriers are correlated. In the proposed algorithm, subcarriers are clustered in blocks, which are allocated the same shuffling pattern with the largest number of the shuffling patterns in the cluster. This way, the signaling overhead can be reduced in comparison with each subcarrier based feedback. Furthermore, the weighted soft decision Viterbi decoding is applied to mitigate noise enhancement inherent to ZF and MMSE linear detectors and improve error rate performance. Simulation results are presented to show the effectiveness of the proposed techniques in frequency-selective MIMO channels.
