Forward cyclic shifted permutation matrix
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 ... WebFeb 18, 2024 · Step 1: to extract the features of the collected initial frame image and multiply it by the permutation matrix many times for obtaining the cyclic matrix of the object image block. In the object tracking task, positive samples are generally obtained only in the object location box provided in the initial frame.

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. WebFig. 1.
