Research of LT Code Based on Key Information Feedback in Deep Space Communication
IEEE Access, 2020 CCSDS LDPC code cannot effectively solve the problems of communication interruptions and high communication error rates in deep space communication. An application scheme of digital fountain code for deep space communication is thoroughly studied in this

A Resource Efficient Ising Model‐Based Quantum Sudoku Solver
Software: 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.

Multilevel LDPC Codes Design for Multimedia Communication CDMA System
EURASIP Journal on Wireless Communications and Networking, 2004 We design multilevel coding (MLC) with a semi-bit interleaved coded modulation (BICM) scheme based on low density parity check (LDPC) codes. Different from the traditional designs, we joined the MLC and BICM together by using the Gray mapping, which is ...

2022 IEEE International Symposium on Information Theory (ISIT), 2022 LDPC codes based on multiple-edge protographs potentially have larger minimum distances compared to their counterparts, single-edge protographs. However, considering different features of their Tanner graph, such as short cycles, girth and other graphical structures, is harder than for Tanner graphs from single-edge protographs.

Radiation‐Induced Fault Detection in Superconducting Quantum Devices
Advanced 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
