Multiplicatively Repeated Non-Binary LDPC Codes [PDF]

open access: yesarXiv, 2010
We propose non-binary LDPC codes concatenated with multiplicative repetition codes. By multiplicatively repeating the (2,3)-regular non-binary LDPC mother code of rate 1/3, we construct rate-compatible codes of lower rates 1/6, 1/9, 1/12,... Surprisingly, such simple low-rate non-binary LDPC codes outperform the best low-rate binary LDPC codes so far ...

Power Consumption of LDPC Decoders in Software Radio [PDF]

open access: yesarXiv, 2011
LDPC code is a powerful error correcting code and has been applied to many advanced communication systems. The prosperity of software radio has motivated us to investigate the implementation of LDPC decoders on processors. In this paper, we estimate and compare complexity and power consumption of LDPC decoding algorithms running on general purpose ...

Quantum LDPC Codes Constructed from Point-Line Subsets of the Finite Projective Plane [PDF]

open access: yesarXiv, 2012
Due to their fast decoding algorithms, quantum generalizations of low-density parity check, or LDPC, codes have been investigated as a solution to the problem of decoherence in fragile quantum states. However, the additional twisted inner product requirements of quantum stabilizer codes force four-cycles and eliminate the possibility of randomly ...

Joint Physical Network Coding and LDPC decoding for Two Way Wireless Relaying [PDF]

open access: yesarXiv, 2013
In this paper, we investigate the joint design of channel and network coding in bi-directional relaying systems and propose a combined low complexity physical network coding and LDPC decoding scheme. For the same LDPC codes employed at both source nodes, we show that the relay can decodes the network coded codewords from the superimposed signal ...

New LDPC Codes Using Permutation Matrices with Higher Girth than QC-LDPC Codes Constructed by Fossorier [PDF]

open access: yesarXiv, 2014
In the literatures, it is well-known that Fossorier code has the girth among LDPC codes. In this paper, we introduce a new class of low-density parity-check (LDPC) codes, with higher girth than other previous constructed codes. Especially we proposed a new method to construct LDPC codes using non fixed shift permutation matrices and full based matrices
