Abstract :
In this paper, the idea of diversification is applied to box-and-match technique and a multi-basis-multi-box decoding algorithm is developed for soft-decision decoding of binary linear block codes. New preprocessing techniques are also employed to improve computational efficiency. These new techniques allow to achieve near maximum likelihood decoding of the (256,131) extended BCH code, which has not been reported so far.
