A Novel Variable-Order Threshold Serial Belief Propagation-Based Decoding Algorithm for LT Codes

IEEE Access
The belief propagation (BP) algorithm is a widely adopted iterative decoding method for Luby transform (LT) codes. However, the conventional log-likelihood ratio BP (LLR-BP) decoder exhibits inherent limitations in additive white Gaussian noise (AWGN ...

Augmented decoders for LDPC codes

EURASIP Journal on Wireless Communications and Networking, 2018
The performance of a belief propagation decoder for low-density parity-check codes is limited by the presence of trapping sets in the code’s graph. This leads to an error floor at higher signal-to-noise ratios.

Belief propagation in imprecise Markov trees [PDF]

, 2009
We replace strong independence in credal networks with the weaker notion of epistemic irrelevance. Focusing on directed trees, we show how to combine the local credal sets in the networks into an overall joint model, and use this to construct and justify

Coarse grained belief propagation for simulation of interacting quantum systems at all temperatures

, 2009
We continue our numerical study of quantum belief propagation initiated in [Phys. Rev. A, 77 (2008), p. 052318]. We demonstrate how the method can be expressed in terms of an effective thermal potential that materializes when the system presents quantum ...

Distributed simultaneous localization and mapping for mobile robot networks via hybrid dynamic belief propagation

International Journal of Distributed Sensor Networks, 2017
This article proposes a hybrid dynamic belief propagation for simultaneous localization and mapping in the mobile robot network. The positions of landmarks and the poses of moving robots at each time slot are estimated simultaneously in an online and ...

Inference Attacks on Genomic Data Based on Probabilistic Graphical Models

Big Data Mining and Analytics, 2020
The rapid progress and plummeting costs of human-genome sequencing enable the availability of large amount of personal biomedical information, leading to one of the most important concerns — genomic data privacy. Since personal biomedical data are highly
