| Abstract(in English) | We consider a soft-decision iterative bounded distance decoding algorithm for binary linear block codes. In the decoding algorithm, bounded distance decodings are carried out with respect to successively input words, called the search centers. A search center is the sum of the hard-decision sequence of a received sequence and a sequence in the set of test patterns which are generated beforehand. The set of test patterns has influence on error performances of the decoding algorithms as simulation results show. In this paper, we propose a construction method of a set of candidate test patterns and a selection method of test patterns based on an introduced measure of effectiveness of test patterns. For several BCH codes of lengths 255 and 511, we show the effectiveness of the proposed method by simulation results. |
