Abstract: A method for estimating error probability of LDPC codes includes ordering LDPC codes according to features in each code with known error characteristics. The method includes identifying features in each LDPC code having known error characteristics; adding each code to one or more categories based on the existence of such features; and ranking the LDPC codes according to the level of error risk.

Abstract: A method for ordering trapping sets to find one or more dominant trapping sets includes analyzing a trapping set and a random set of codewords to generate a distance value for each trapping set, and ordering the trapping sets by the distance value. Distance values may be determined for each trapping set by tracking a vote count wherein a correct decode at a certain noise level produces a “right” vote and an incorrect decode at a certain noise level produces a “left” vote. A certain threshold number of “left” votes terminates processing at that noise level.
Abstract translation: 用于排序陷阱集合以找到一个或多个主要捕获集合的方法包括分析陷阱集合和随机的码字集合以生成每个陷阱集合的距离值，并且将陷阱集合排序距离值。 可以通过跟踪投票计数来确定每个陷阱集合的距离值，其中在某一噪声级别的正确解码产生“正确”投票，并且在某一噪声电平处产生不正确的解码产生“左”投票。 一定数量的“左”选票终止在该噪声级别的处理。
