This paper proposes a demodulation scheme based on channel prediction for differential multiple-input multiple-output (MIMO) spatial multiplexing employing per transmit antenna differential mapping (PADM). As PADM is one of differential space-time trellis coding (DSTTC), it has to employ per-survivor processing (PSP) based on the Viterbi algorithm (VA) for its demodulation. Therefore, PADM has excellent tracking performance on fast time-varying channels. However, aiming at higher frequency efficiency, PADM for higher modulation index suffers from the following two disadvantages: (1) poor sensitivity performance; (2) large computational complexity. In order to solve the disadvantages of (1) and (2), this paper employs spatial multiplexing structure and state reduction algorithm for the VA, i.e., decision-feedback sequence estimation (DFSE), respectively. Finally, in the case of 4bps/Hz and 2 receive antennas, computer simulation results confirm that the proposed scheme has excellent BER performance on fast time-varying channels in the case of the maximum Doppler frequency normalized by symbol rate of 4%. |
