More Information
Summary:A non-soft decision decoding algorithm for binary linear block codes transmitted over AWGN channel is presented. Unlike soft decision decoding algorithms, the proposed algorithm does not computing weighted Hamming distances. Based on the majority of code word candidates from the hard decision decoding output, the proposed algorithm improves error-correcting performance by 1 dB of coding gain compared to that of hard decision decoding algorithms. Also, a schematic block diagram for finding the codeword of majority is developed. Furthermore, a comparison of hardware complexity is made between the computation of weighted Hamming distances and the finding of majority code word.
