Absorbing Set Analysis and Design of LDPC Codes from Transversal Designs over the AWGN Channel [PDF]

, 2014
In this paper we construct low-density parity-check (LDPC) codes from transversal designs with low error-floors over the additive white Gaussian noise (AWGN) channel. The constructed codes are based on transversal designs that arise from sets of mutually

Advanced channel coding for space mission telecommand links

, 2013
We investigate and compare different options for updating the error correcting code currently used in space mission telecommand links. Taking as a reference the solutions recently emerged as the most promising ones, based on Low-Density Parity-Check ...

Tanner $(J,L)$ Quasi-Cyclic LDPC Codes: Girth Analysis and Derived Codes

IEEE Access, 2019
Girth plays an important role in the design of low-density parity-check (LDPC) codes. Motivated by the works on the girth of some classes of Tanner quasi-cyclic (QC) LDPC codes, e.g., Tanner (3, 5), (3, 7), (3, 11), and (5, 7) codes, we, in this paper ...

Rate-Equivocation Optimal Spatially Coupled LDPC Codes for the BEC Wiretap Channel

, 2011
We consider transmission over a wiretap channel where both the main channel and the wiretapper's channel are Binary Erasure Channels (BEC). We use convolutional LDPC ensembles based on the coset encoding scheme.

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.

Comparison of LDPC block and LDPC convolutional codes based on their decoding latency

2012 7th International Symposium on Turbo Codes and Iterative Information Processing (ISTC), 2012
We compare LDPC block and LDPC convolutional codes with respect to their decoding performance under low decoding latencies. Protograph based regular LDPC codes are considered with rather small lifting factors. LDPC block and convolutional codes are decoded using belief propagation.

Reliability Ratio Based Weighted Bit-Flipping Decoding for LDPC Codes

, 2005
In this contribution, a novel reliability-ratio based weighted bit-flipping(RRWBF) algorithm is proposed for decoding Low Density Parity Check (LDPC) codes.

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 ...
