4-CYCLE FREE APM LDPC CODES WITH AN EXPLICIT CONSTRUCTION [PDF]
Journal of Algebraic Systems, 2021 Recently, a class of low-density parity-check codes based on affine permutation matrices, called APM-LDPC codes, have been considered which have some advantages than quasi-cyclic (QC) LDPC codes in terms of minimum-distance, cycle distribution, and error-

Area‐ and energy‐efficient high‐throughput QC‐LDPC encoder for space applications
Electronics Letters, Volume 59, Issue 23, December 2023., 2023 An area‐ and energy‐efficient encoding method and encoder architecture are proposed using a bit selector before bit XOR operations in vector–matrix multiplication. A fully parallel low‐density parity check encoder is implemented on the aiwan Semiconductor Manufacturing Company (TSMC) 90 nm complementary metal oxide semiconductor (CMOS) technology ...

ON THE CLASS OF ARRAY-BASED APM-LDPC CODES [PDF]
Journal of Algebraic Systems, 2021 We construct an explicit class of affine permutation matrix low-density parity-check (APM-LDPC) codes based on the array parity-check matrix by using two affine maps f (x) = x-1 and g(x) = 2x-1 on Z_m, where m is an odd prime number, with girth 6 and ...

Embedded Parallel Implementation of LDPC Decoder for Ultra‐Reliable Low‐Latency Communications
Applied Computational Intelligence and Soft Computing, Volume 2023, Issue 1, 2023., 2023 Ultra‐reliable low‐latency communications, URLLC, are designed for applications such as self‐driving cars and telesurgery requiring a response in milliseconds and are very sensitive to transmission errors. To match the computational complexity of LDPC decoding algorithms to URLLC applications on IoT devices having very limited computational resources ...

Performance analysis of LDPC coded GFDM systems
IET Communications, Volume 16, Issue 14, Page 1663-1673, August 2022., 2022 Abstract This paper analyzes the error probability performance of low‐density parity‐check (LDPC) coded generalized frequency division multiplexing (GFDM) systems over Rayleigh fading and additive white Gaussian noise (AWGN) channels. The initial log‐likelihood ratio (LLR) expressions used in the sum‐product algorithm (SPA) decoder are first derived ...

DNN‐aided read‐voltage threshold optimization for MLC flash memory with finite block length
IET Communications, Volume 16, Issue 2, Page 120-130, January 2022., 2022 Abstract The error‐correcting performance of multi‐level‐cell (MLC) NAND flash memory is closely related to the block length of error‐correcting codes (ECCs) and log‐likelihood‐ratios of the read‐voltage thresholds. Driven by this issue, this paper optimizes the read‐voltage thresholds for MLC flash memory to improve the decoding performance of ECCs ...
