In this paper, we propose a peak power reduction method for LDPC coded OFDM system, where transmit data sequence is grouped into several clusters based on structure of a low density parity-check matrix and the phase or each cluster is adjusted so as to minimize PAPR of OFDM signal by multip...
An identification scheme based on parity check matrix of error-correcting codes over GF(2) was proposed in the paper "A New Paradigm for Public Key Identification" by J. Stern(1996), a new identification scheme based on parity check matrix of rank distance codes over GF(qN) (q is a prim...
matrix are associated with corresponding data bits of the storage medium, rows of the parity-check matrix are associated with check bits, and each matrix element of the parity-check matrix having a predefined value indicates a connection between a particular data bit and a particular check bit. ...
Aspects of the present disclosure relate to parity-check matrix (P-matrix) rotation in low-density parity check (LDPC) coding. The P-matrix rotation may be performed by a plurality of shift registers, where each shift register is configured to receive a respective set of bits corresponding to...
