Design and Performance of Rate-compatible Non-Binary LDPC Convolutional Codes

open access: yes, 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.

Block Markov superposition transmission of LDPC codes

open access: yesJournal of Information and Intelligence, 2023
In this paper, based on the block Markov superposition transmission (BMST) technique, we present a new class of coupled low-density parity-check (LDPC) codes for the transport block (TB)-based transmission to improve the error-correcting performance. For

Quasi-cyclic multi-edge LDPC codes for long-distance quantum cryptography [PDF]

open access: yesnpj Quantum Information, 2017
The speed at which two remote parties can exchange secret keys in continuous-variable quantum key distribution (CV-QKD) is currently limited by the computational complexity of key reconciliation.

An Iteratively Decodable Tensor Product Code with Application to Data Storage [PDF]

open access: yes, 2010
The error pattern correcting code (EPCC) can be constructed to provide a syndrome decoding table targeting the dominant error events of an inter-symbol interference channel at the output of the Viterbi detector.

Design of Multiple-Edge Protographs for QC LDPC Codes Avoiding Short Inevitable Cycles [PDF]

open access: yes, 2012
There have been lots of efforts on the construction of quasi-cyclic (QC) low-density parity-check (LDPC) codes with large girth. However, most of them are focused on protographs with single edges and little research has been done for the construction of QC LDPC codes lifted from protographs with multiple edges.

Analysis of Quasi-Cyclic LDPC codes under ML decoding over the erasure channel [PDF]

open access: yes, 2010
In this paper, we show that Quasi-Cyclic LDPC codes can efficiently accommodate the hybrid iterative/ML decoding over the binary erasure channel. We demonstrate that the quasi-cyclic structure of the parity-check matrix can be advantageously used in ...

Investigating the Performance of Coded GSIM DCSK Communication Systems over Multipath Rayleigh Fading Channel

open access: yesJournal of Communications Software and Systems
Index modulation−based differential chaos shift keying (IM−DCSK) is a promising technique in wireless communication systems. Among all schemes, a Grouping Subcarrier Index Modulation DCSK (GSIM−DCSK) supports suit−coded modulation to improve bit error ...

A 588-Gb/s LDPC Decoder Based on Finite-Alphabet Message Passing [PDF]

open access: yesIEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2017
An ultrahigh throughput low-density parity-check (LDPC) decoder with an unrolled full-parallel architecture is proposed, which achieves the highest decoding throughput compared to previously reported LDPC decoders in the literature.

Design and Analysis of Time-Invariant SC-LDPC Convolutional Codes With Small Constraint Length

open access: yes, 2017
In this paper, we deal with time-invariant spatially coupled low-density parity-check convolutional codes (SC-LDPC-CCs). Classic design approaches usually start from quasi-cyclic low-density parity-check (QC-LDPC) block codes and exploit suitable ...
