Analysis of TDMP Algorithm of LDPC Codes Based on Density Evolution and Gaussian Approximation [PDF]

open access: yesEntropy, 2019
Based on density evolution analysis of the existing belief propagation (BP) algorithm, the Turbo Decoding Message Passing (TDMP) algorithm was analyzed from the perspective of density evolution and Gaussian approximation, and the theoretical analysis ...

Dynamics, Noise, Delays and the Gibbs and Conditional Entropy [PDF]

open access: yesEntropy
In this paper we review the concepts of the Gibbs and conditional entropies and examine their dynamic behaviour when the underlying dynamics are described by ordinary differential equations or stochastic differential equations. We then go on to introduce

Threshold Computation for Spatially Coupled Turbo-Like Codes on the AWGN Channel

open access: yesEntropy, 2021
In this paper, we perform a belief propagation (BP) decoding threshold analysis of spatially coupled (SC) turbo-like codes (TCs) (SC-TCs) on the additive white Gaussian noise (AWGN) channel.

Efficient Design of Read Voltages and LDPC Codes in NAND Flash Memory Using Density Evolution

open access: yesIEEE Access, 2023
Low-density parity-check (LDPC) codes play an important role in the reliability enhancement of commercial NAND flash memory. Unfortunately, due to the requirement of the reading speed of NAND flash memory, the LDPC decoder will not obtain precise soft ...

Effect of high-pressure sintering on snow density evolution: experiments and results

open access: yesJournal of Glaciology, 2022
Very few studies have emphasized the effects of high-pressure sintering on snow density evolution, even though snow as a type of engineering material is widely used in construction engineering in cold regions for snow pavement, snow runway and polar ...
