CLEAR Interference Cancellation in a Wideband Dual‐Channel Receiver for Independent Satellite Multi‐Connectivity Links

open access: yesInternational Journal of Satellite Communications and Networking, Volume 44, Issue 6, Page 689-699, November/December 2026.
ABSTRACT In this paper, the correlation learning estimation and adaptive reduction (CLEAR) of interference, an adaptive, blind and transparent interference compensation method applied in a wideband dual‐channel receiver, is studied for a pair of independent satellite multi‐connectivity links, using the same carrier frequency and signal bandwidth in use

HELIOS ‐ Highly rEliable Links durIng sOlar conjunctionS

open access: yesRadio Science, Volume 61, Issue 8, August 2026.
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]

open access: yes, 2006
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.

Channel code division multiple access and its multilevel structured LDPC based instantiation

open access: yes, 2008
In this paper, we introduce and outline the concept of Channel Code Division Multiple Access (CCDMA) using a design example based on the recently proposed Multilevel Structured (MLS) LDPC codes. We succeeded in making the memory requirements of the multi-

A Resource Efficient Ising Model‐Based Quantum Sudoku Solver

open access: yesSoftware: Practice and Experience, Volume 56, Issue 6, Page 643-657, June 2026.
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.

Cooperative MIMO Communication at Wireless Sensor Network: An Error Correcting Code Approach

open access: yesSensors, 2011
Cooperative communication in wireless sensor network (WSN) explores the energy efficient wireless communication schemes between multiple sensors and data gathering node (DGN) by exploiting multiple input multiple output (MIMO) and multiple input single ...

Radiation‐Induced Fault Detection in Superconducting Quantum Devices

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 4, April 2026.
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

Digital image information hiding algorithm research based on LDPC code

open access: yesEURASIP Journal on Image and Video Processing, 2018
LDPC (low-density parity-check code) is a parity check code, and its performance is very close to Shannon limit. It is a sort of good channel code which has good ability of error correction. The coding can be introduced to an information-hiding algorithm

Fast bootstrap and reliable readout using hidden references for DNA data storage

open access: yesiMeta, Volume 5, Issue 1, February 2026.
This study provides a bootstrap readout framework for DNA data storage based on multiple‐fold hidden references. We employ a multi‐stage alignment and error correction strategy, transforming the de novo readout into a resequencing‐like workflow. Correlation to the hidden watermark reference identifies low‐error‐rate reads, and bit‐wise consensus ...
