Forward cyclic shifted permutation matrix
WebOther values indicate that the number of columns a blocksize -by- blocksize diagonal matrix must be cyclically shifted to the right. Each submatrix is either a zero matrix or a cyclically shifted version of a diagonal matrix. Data Types: double Output Arguments collapse all H — Parity-check matrix sparse logical matrix 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.

WebCyclic delay-diversity (CDD) [DK01, GSP02], a.k.a. cyclic shift diversity, is an adaptation of the generalized delay-diversity (GDD) scheme (see Section 11.4.1) to OFDM systems. The idea is to send on each antenna a circularly shifted version of the same OFDM symbol in the time domain. Hence, the temporal delay introduced on each antenna in the ...
