Performance analysis on joint channel decoding and state estimation in cyber-physical systems
EURASIP Journal on Wireless Communications and Networking, 2017 We propose to use an mean square error (MSE) transfer chart to evaluate the performance of the proposed belief propagation (BP)-based channel decoding and state estimation scheme.

Learned Decimation for Neural Belief Propagation Decoders
CoRR, 2020 We introduce a two-stage decimation process to improve the performance of neural belief propagation (NBP), recently introduced by Nachmani et al., for short low-density parity-check (LDPC) codes. In the first stage, we build a list by iterating between a conventional NBP decoder and guessing the least reliable bit.

Optimization of graph based codes for belief propagation decoding [PDF]
2014 IEEE Information Theory Workshop (ITW 2014), 2014 A low-density parity-check (LDPC) code is a linear block code described by a sparse parity-check matrix, which can be efficiently represented by a bipartite Tanner graph. The standard iterative decoding algorithm, known as belief propagation, passes messages along the edges of this Tanner graph.
