Error control performance of the(16, 7) minimum-banwidth binary error control line code (MB-ECLC) according to decoding algorithms is analyzed and compared in this paper. As a result, when retransimissionisnot allowed or meaningless, to reduce performance degradation and computationl burden, the modified soft decision decoding algorithm using thestructure of (16, 7) MB-ECLC is proposed. The error control capability of this modified algorithm is far better than that of a hard decision decoding algorithm, and almost same as that of a full soft decision decoding algorithm . In additino the number of comparisons for the modified algorithm is decreased more than 5 times as compared with a full soft decision decoding algorithm.
