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 presents a new construction of punctured-node protograph-based Raptor-like
(PN-PBRL) codes that is suitable for long-blocklength applications. As with the Raptor …

Density evolution for protograph low-density parity-check (LDPC) codes is considered, and it
is shown that the message-error rate falls double-exponentially with iterations whenever the …

This paper presents a simple yet effective method for designing nested families of LDPC
codes. Rate compatible codes are essential for many communication applications, eg hybrid …

In this paper, families of rate-compatible protograph-based LDPC codes that are suitable for
incrementalredundancy hybrid ARQ applications are constructed. A systematic technique to …

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 …

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 …

We propose several LDPC code constructions that simultaneously achieve good threshold
and error floor performance. Minimum distance is shown to grow linearly with block size …

This paper deals with the problem of devising an efficient framework for constructing rate-
compatible low-density parity-check (RC-LDPC) codes. We present a deterministic …

This article describes the different methods to design regular low density parity-check
(LDPC) codes with large girth. In graph terms, this corresponds to designing bipartite …
