Abstract :
This paper proposes a fast soft decision decoding algorithm for binary linear block code. Based on error weights, decoding complexity is significantly reduced at the expense of about 0.1 to 0.5 dB coding again inferior to that of maximum likelihood decoding at block error rate of 10-5. And in terms of test patterns, decoding complexity is reduced to 20% on average, compared to that of Chase-II algorithm with d _min-1 tested positions
