Low-density parity-check (LDPC) codes have attracted much attention over the past two
decades since they can asymptotically approach the Shannon capacity in a variety of data …

We investigate the performance of the protograph low-density parity-check (LDPC) codes,
which have been shown to possess simple structures and outstanding error performance …

In this paper, we investigate the attainable performance of quasi-cyclic (QC) protograph low-
density parity-check (LDPC) codes for transmission over both additive white Gaussian noise …

This paper provides a comprehensive analysis of nonbinary low-density parity check
(LDPC) codes built out of protographs. We consider both random and constrained edge …

A construction method for protograph-based LDPC codes that simultaneously achieve low
iterative decoding threshold and linear minimum distance is proposed. We start with a high …

Double protograph low-density parity-check code has been shown to be a good solution for
joint source-channel coding. Moreover, the source code and channel code (as one code …

This paper proposes protograph-based Raptor-like (PBRL) codes as a class of rate-
compatible low-density parity-check codes for binary-input AWGN channels. As with the …

This paper produces a rate-compatible protograph LDPC code at 1k information blocklength
with superior performance in both waterfall and error floor regions. The design of such codes …

Low-density parity-check (LDPC) convolutional codes are capable of achieving excellent
performance with low encoding and decoding complexity. In this paper, we discuss several …

A block-fading (BF) channel, also known as a slow-fading channel, is a type of simple and
practical channel model that can characterize the primary feature of a number of wireless …
