Performance of Spatially-Coupled LDPC Codes and Threshold Saturation over BICM Channels [PDF]
arXiv, 2013 We study the performance of binary spatially-coupled low-density parity-check codes (SC-LDPC) when used with bit-interleaved coded-modulation (BICM) schemes. This paper considers the cases when transmission takes place over additive white Gaussian noise (AWGN)channels and Rayleigh fast-fading channels.

Jointly designed quasi-cyclic LDPC-coded cooperation with diversity combining at receiver
International Journal of Distributed Sensor Networks, 2020 This correspondence proposes a jointly-designed quasi-cyclic (QC) low-density parity-check (LDPC)-coded multi-relay cooperation with a destination node realized by multiple receive antennas.

Free Pseudodistance Growth Rates for Spatially Coupled LDPC Codes over the BEC [PDF]
arXiv, 2018 The minimum pseudoweight is an important parameter related to the decoding performance of LDPC codes with iterative message-passing decoding. In this paper, we consider ensembles of periodically time-varying spatially coupled LDPC (SC-LDPC) codes and the pseudocodewords arising from their finite graph covers of a fixed degree. We show that for certain $

A Survey on Programmable LDPC Decoders
IEEE Access, 2016 Low-density parity-check (LDPC) block codes are popular forward error correction schemes due to their capacity-approaching characteristics. However, the realization of LDPC decoders that meet both low latency and high throughput is not a trivial challenge.

Optimizing Polar Codes Compatible with Off-the-Shelf LDPC Decoders [PDF]
arXiv, 2019 Previous work showed that polar codes can be decoded using off-the-shelf LDPC decoders by imposing special constraints on the LDPC code structure, which, however, resulted in some performance degradation. In this paper we show that this loss can be mitigated; in particular, we demonstrate how the gap between LDPC-style decoding and Arikan's Belief ...

Optics Express, 2016 Mode-division multiplexing over fibers has attracted increasing attention over the last few years as a potential solution to further increase fiber transmission capacity. In this paper, we demonstrate the viability of orbital angular momentum (OAM) modes

Design of rate-compatible low-density parity-check codes for type-II hybrid ARQ systems
Tongxin xuebao, 2006 The design of powerful rate-compatible low-density parity-check codes（RC-LDPC）was constructed in zigzag structure for type-II hybrid ARQ systems.The generalized PEG algorithm was used in the process of constructing RC-LDPC codes to improve the ...

Analysis of Non-binary Hybrid LDPC Codes [PDF]
arXiv, 2008 In this paper, we analyse asymptotically a new class of LDPC codes called Non-binary Hybrid LDPC codes, which has been recently introduced. We use density evolution techniques to derive a stability condition for hybrid LDPC codes, and prove their threshold behavior.
