A New Density Evolution Approximation for LDPC and Multi-Edge Type LDPC Codes [PDF]
IEEE Transactions on Communications, 2016 This paper considers density evolution for lowdensity parity-check (LDPC) and multi-edge type low-density parity-check (MET-LDPC) codes over the binary input additive white Gaussian noise channel. We first analyze three singleparameter Gaussian approximations for density evolution and discuss their accuracy under several conditions, namely at low rates,

Cost‐Effective DNA Storage System with DNA Movable Type
Advanced Science, Volume 12, Issue 9, March 6, 2025.This study presents a cost‐effective “DNA‐movable‐type storage” system inspired by movable type printing. Utilizing reusable prefabricated DNA‐MTs and an automated inkjet printer, BISHENG‐1 stores and retrieves 43.7 KB of data in vitro and in vivo with only 350 DNA‐MTs, achieving storage costs of $122 MB−1–significantly more cost‐efficient than ...

Electronics Letters, Volume 61, Issue 1, January/December 2025.Here, a multi‐user signal iterative detection and decoding scheme named LBEP based on block expectation propagation (BEP) is proposed for LDPC‐coded two‐phase unsourced random access (URA) scheme. In the iteratively process, the approximation of matrix inversion is used to facilitate expectation propagation (EP). The numerical results show that, in the

Generalized simplified variable-scaled min sum LDPC decoder for irregular LDPC codes [PDF]
2014 IEEE 25th Annual International Symposium on Personal, Indoor, and Mobile Radio Communication (PIMRC), 2014 In this paper, we propose a novel low complexity scaling strategy of min-sum decoding algorithm for irregular LDPC codes. In the proposed method, we generalize our previously proposed simplified Variable Scaled Min-Sum (SVS-min-sum) by replacing the sub-optimal starting value and heuristic update for the scaling factor sequence by optimized values ...
