The invention presents a combinational fuzzy-decision Viterbi decoder, which combines the modified II and S-membership functions, to further improve the performance of the dedicated short-range communications (DSRC) system operated in the time-varying fading channel. The combinational fuzzy-decision constellation decoder and analog Viterbi decoder. The coding gain of the DSRC system using the proposed combinational fuzzy-decision Viterbi decoder is compared with both the hard-decision and soft-decision Viterbi decoder for the BPSK, QPSK, 16-QAM and 64-QAM OFDM DSRC systems. The improvement in performance of the DSRC system achieved by replacing the hard decision and soft decision Viterbi decoder with the proposed combinational fuzzy-decision Viterbi decoder will be validated with simlations.
