摘要： Apparatus having corresponding methods and tangible computer-readable medium embodying instructions executable by a computer to perform the methods comprise: a receiver adapted to receive a signal representing an input code block, wherein the input code block represents information encoded with a (N, K) difference-set cyclic code, wherein the input code block includes N symbols, and wherein the N symbols represent K bits of the information; an estimator adapted to estimate a signal-to-noise ratio of the signal; a raised-threshold majority-logic decoder adapted to decode the input code block according to a raised-threshold majority-logic decoding algorithm when the signal-to-noise ratio does not exceed a first predetermined threshold; and a variable-threshold majority-logic decoder adapted to decode the input code block according to a variable-threshold majority-logic decoding algorithm when the signal-to-noise ratio exceeds the first predetermined threshold.
