Split-extended LDPC codes for coded cooperation [PDF]
2010 International Symposium On Information Theory & Its Applications, 2010 We propose a new code design that aims to distribute an LDPC code over a relay channel. It is based on a split-and-extend approach, which allows the relay to split the set of bits connected to some parity-check of the LDPC code into two or several subsets. Subsequently, the sums of bits within each subset are used in a repeat-accumulate manner in order

Design and Performance of Rate-compatible Non-Binary LDPC Convolutional Codes
, 2011 In this paper, we present a construction method of non-binary low-density parity-check (LDPC) convolutional codes. Our construction method is an extension of Felstroem and Zigangirov construction for non-binary LDPC convolutional codes.

Tradeoffs for reliable quantum information storage in surface codes and color codes [PDF]
, 2013 The family of hyperbolic surface codes is one of the rare families of quantum LDPC codes with non-zero rate and unbounded minimum distance. First, we introduce a family of hyperbolic color codes.

Scene‐Driven Semantic Alignment for Generative Communication in Underwater Images
IET Signal Processing, Volume 2026, Issue 1, 2026.Underwater images serve as one of the most intuitive media for human perception of underwater environments. However, the limited bandwidth and susceptibility to noise in underwater acoustic (UWA) channels pose significant challenges for traditional image encoding and transmission methods, thereby hindering high‐quality image reconstruction.

Encoding of QC-LDPC Codes of Rank Deficient Parity Matrix
Journal of Engineering, 2016 the encoding of long low density parity check (LDPC) codes presents a challenge compared to its decoding. The Quasi Cyclic (QC) LDPC codes offer the advantage for reducing the complexity for both encoding and decoding due to its QC structure.

A Flexible LDPC/Turbo Decoder Architecture [PDF]
, 2010 Low-density parity-check (LDPC) codes and convolutional Turbo codes are two of the most powerful error correcting codes that are widely used in modern communication systems. In a multi-mode baseband receiver, both LDPC and Turbo decoders may be required.

Journal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.The sixth generation (6G) wireless networks are used to provide a large coverage, and also this generation needed to support different emerging applications in harsh areas with higher user equipment mobility. For the above case, a new modulation technique called orthogonal time–frequency space (OTFS) modulation has emerged as a promising technique to ...
