Efficient LDPC Encoder Design for IoT-Type Devices
Low-density parity-check (LDPC) codes are known to be one of the best error-correction coding (ECC) schemes in terms of correction performance. They have been utilized in many advanced data communication standards for which the codecs are typically ...

HELIOS ‐ Highly rEliable Links durIng sOlar conjunctionS
Abstract During deep space missions, maintaining reliable communication between a spacecraft and Earth becomes particularly challenging during superior solar conjunctions, when the spacecraft passes behind the Sun relative to Earth. The highly ionized solar corona and solar wind create plasma inhomogeneities that severely affect radio signals, leading ...

Design of LDPC Codes: A Survey and New Results [PDF]
This survey paper provides fundamentals in the design of LDPC codes. To provide a target for the code designer, we first summarize the EXIT chart technique for determining (near-)optimal degree distributions for LDPC code ensembles.

Spatially Coupled Generalized Low-Density Parity-Check Codes Over Class-A Impulsive Noise Channels
In this paper, a class of spatially coupled generalized low-density parity-check (SC-GLDPC) codes with minimum coupling width is introduced to mitigate the Class-A impulsive noise. Codes with minimum coupling width are beneficial to simple code structure,

A Resource Efficient Ising Model‐Based Quantum Sudoku Solver
ABSTRACT Background Quantum algorithms exploit superposition and parallelism to address complex combinatorial problems, many of which fall into the non‐polynomial (NP) class. Sudoku, a widely known logic‐based puzzle, is proven to be NP‐complete and thus presents a suitable testbed for exploring quantum optimization approaches.

Radiation‐Induced Fault Detection in Superconducting Quantum Devices
Cosmic rays cause correlated errors in superconducting quantum computers. Quantum error correction codes are not sufficient to solve this issue, as such a real‐time logical detector for radiation faults has been developed. It identifies radiation faults with high accuracy, providing information which could be used to revert the effects of radiation and

Low-rate coding using incremental redundancy for GLDPC codes [PDF]
In this paper we propose a low-rate coding method, suited for application-layer forward error correction. Depending on channel conditions, the coding scheme we propose can switch from a fixed-rate LDPC code to various low-rate GLDPC codes.

Distributed QC-LDPC Coded Spatial Modulation for Half-Duplex Wireless Communications [PDF]
The bit error rate (BER) performance of spatial modulation (SM) can be further improved by applying quasi-cyclic low-density parity-check (QC-LDPC) codes recommended in 5G to SM.
