Dithered Belief Propagation Decoding

IEEE Transactions on Communications, 2012
We introduce two dithered belief propagation decoding algorithms to lower the error floor with a minimal hardware overhead. One of the algorithms can additionally improve the decoding performance in the waterfall region using a large iteration limit but with a negligible increase in the average time complexity.

Analog Digital Belief Propagation

open access: yesIEEE Communications Letters, 2012
We introduce a message passing belief propagation (BP) algorithm for factor graph over linear models that uses messages in the form of Gaussian-like distributions. With respect to the regular Gaussian BP, the proposed algorithm adds two operations to the model, namely the wrapping and the discretization of variables.

Computational models of belief propagation [PDF]

open access: yes, 2015
In this thesis we aim to gain better understanding on the working of the belief propagation algorithm designed for graphical models in other computational frameworks like the neural systems, as well as the error associated with loopy belief propagation in Bayesian networks.

Cooperative Localization Using Posterior Linearization Belief Propagation [PDF]

open access: yesIEEE Transactions on Vehicular Technology, 2018
This paper presents the posterior linearization belief propagation (PLBP) algorithm for cooperative localization in wireless sensor networks with nonlinear measurements. PLBP performs two steps iteratively: linearization and belief propagation.
