WebThe circulant weight of a permutation matrix refers to the number of cyclic shift identity matrices superimposed by the permutation matrix. Regarding the circulant weight of permutation matrix P, NR discussed two different design schemes with maximum cyclic weight of 1 and 2, respectively. 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. pregnancy at 21 years oldThe trace of a permutation matrix is the number of fixed points of the permutation. If the permutation has fixed points, so it can be written in cycle form as π = (a1) (a2)... (ak)σ where σ has no fixed points, then ea1,ea2,...,eak are eigenvectors of the permutation matrix.
