An encrypting block low-density parity-check code based on quadratic permutation polynomials (QPPs) (QPP-Block-LDPC) is proposed in this paper. The parity-check matrix of the encrypting QPP-Block-LDPC code is composed of a group of permutations, whic

A frequency-domain channel expanding technique (FD-CET) is proposed for channel estimation in an iterative receiver of a low-density parity-check coded orthogonal frequency division multiplexing system. The FD-CET can expand a subset of the frequency

A concatenated code model is proposed for high-order low-density parity-check (LDPC) coded modulations. A corresponding concatenated-code belief propagation (CCBP) decoding algorithm is derived for our proposed concatenated code. Moreover, the design
