WebDec 2, 2013 · First using an algorithm with lower computational complexity, all the cycles in the parity check matrix H are found. Then following a ruler, we adjust the shift value of circulant permutation matrix (CPM) to remove the short-cycles. This algorithm could ensure that the code after cycle removal process preserves the quasi-cyclic structure. In mathematics, and in particular in group theory, a cyclic permutation (or cycle) is a permutation of the elements of some set X which maps the elements of some subset S of X to each other in a cyclic fashion, while fixing (that is, mapping to themselves) all other elements of X. If S has k elements, the cycle is called a k-cycle. Cycles are often denoted by the list of their elements enclosed with parentheses, in the order to which they are permuted. gareth sullivanWebNov 17, 2015 · Supplementary material available at Biometrika online includes the analyses of additional genomic datasets, the proof of Lemma A1, simulations illustrating the resampling distributions defined in § 2.3, and an analysis comparing cyclic shift and random row-by-row permutation.
