Optimized Design of Distributed Quasi-Cyclic LDPC Coded Spatial Modulation. [PDF]
Sensors (Basel), 2023 We propose a distributed quasi-cyclic low-density parity-check (QC-LDPC) coded spatial modulation (D-QC-LDPCC-SM) scheme with source, relay and destination nodes. At the source and relay, two distinct QC-LDPC codes are used.

Quantum Coding via Quasi-Cyclic Block Matrix. [PDF]
Entropy (Basel), 2023 An effective construction method for long-length quantum code has important applications in the field based on large-scale data. With the rapid development of quantum computing, how to construct this class of quantum coding has become one of the key ...

Optimizing quasi-cyclic spatially coupled LDPC codes by eliminating harmful objects
EURASIP Journal on Wireless Communications and Networking, 2023 It is well known that some harmful objects in the Tanner graph of low-density parity-check (LDPC) codes have a negative impact on their error correction performance under iterative message-passing decoding.

International Journal of Engineering and Advanced Technology, 2019 Nowadays, all our information are kept in electronic form using the internet and trust that it cannot be accessed by anyone except the intended recipient. For the sake of this purpose, digital signature schemes play a significant role in providing authenticity and record management efficiency.

Automorphism Ensemble Decoding of Quasi-Cyclic LDPC Codes by Breaking Graph Symmetries [PDF]
IEEE Communications Letters, 2022 We consider automorphism ensemble decoding (AED) of quasi-cyclic (QC) low-density parity-check (LDPC) codes. Belief propagation (BP) decoding on the conventional factor graph is equivariant to the quasi-cyclic automorphisms and therefore prevents gains ...

FINDING INFORMATION SETS WHEN CORRECTING ERROR BURSTS WITH QUASI-CYCLIC CODES
T-Comm, 2023 This article discusses the question of assessing the probability of finding information sets in block-permutation and block-circulant matrices. Traditionally, interference-resistant coding is considered independent errors, however, in real systems they ...

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

Quasi-Cyclic Stern Proof of Knowledge [PDF]
International Symposium on Information Theory, 2021 The ongoing NIST standardization process has shown that Proof of Knowledge (PoK) based signatures have become an important type of possible post-quantum signatures. Regarding code-based cryptography, the main original approach for PoK based signatures is

Quasi-cyclic subcodes of cyclic codes [PDF]
, 2016 We completely characterize possible indices of quasi-cyclic subcodes in a cyclic code for a very broad class of cyclic codes. We present enumeration results for quasi-cyclic subcodes of a fixed index and show that the problem of enumeration is equivalent

New binary and ternary quasi-cyclic codes with good properties [PDF]
Computational and Applied Mathematics, 2021 One of the most important and challenging problems in coding theory is to construct codes with best possible parameters and properties. The class of quasi-cyclic (QC) codes is known to be fertile to produce such codes.
