List-Based Residual Belief-Propagation Decoding of LDPC Codes

IEEE Communications Letters
This letter presents an enhanced list-based residual belief propagation (L-RBP) method for decoding low-density parity-check (LDPC) codes. L-RBP reduces computational complexity by scheduling a concise list of residuals.

An Improved Belief Propagation Decoding of BATS Codes

2019 IEEE 19th International Conference on Communication Technology (ICCT), 2019
In this paper, we propose an improved belief propagation (BP) decoding algorithm for decoding BATS codes. In the traditional BP decoding, the BP decoder decodes the input packets only when the rank equals to the degree of the efficient matrix for a batch.

Approximate Belief Propagation Decoder for Polar Codes

2018 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2018
Polar code is increasing its popularity recently for its capacity-achieving property for B-DMCs. However, when designing decoders for polar code, it has always been an inevitable concern for us to balance the decoding performance and the hardware consumption.

Bipartite Belief Propagation Polar Decoding With Bit-Flipping

ICASSP 2020 - 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2020
For the scenarios with high throughput requirements, the belief propagation (BP) decoding is one of the most promising decoding strategies for polar codes. By pruning the redundant variable nodes (VNs) and check nodes (CNs) in the original factor graph, the graph is condensed to a sparse bipartite graph which is similar to the graph for low-density ...

Performance Study of a Class of Irregular LDPC Codes through Low Complexity Bounds on Their Belief-Propagation Decoding Thresholds

AEIT International Annual Conference, 2019
This paper investigates about the usefulness of some recently published low complexity upper bounds on belief-propagation decoding thresholds for irregular low-density parity-check (LDPC) codes to analyze their performance on memoryless binary input ...

Convolutional Neural Network-Aided Bit-Flipping for Belief Propagation Decoding of Polar Codes

IEEE International Conference on Acoustics, Speech, and Signal Processing, 2019
Known for their capacity-achieving abilities, polar codes have been selected as the control channel coding scheme for 5G communications. To satisfy high throughput and low latency, belief propagation (BP) is ideal as the decoding algorithm due to its ...

Syndrome-Generalized Belief Propagation Decoding for Quantum Memories

ICC 2019 - 2019 IEEE International Conference on Communications (ICC), 2019
Quantum low-density parity check (QLDPC) codes are promising in realization of scalable, fault tolerant quantum memory for computation. Many of the QLDPC codes constructions suffer from unavoidable short cycles in their Tanner graph which degrade the ...

Synthesizing LDPC Belief Propagation Decoding with Molecular Reactions

2018 IEEE International Conference on Communications (ICC), 2018
This paper proposes a CRN-based implementation approach for low-density parity-check (LDPC) decoding based on belief propagation (BP). Since the belief (probability) can be naturally mapped to molecule concentration, LDPC decoding can be realized with CRNs instead of silicon based hardware.

Efficient Belief Propagation List Decoding of Polar Codes

2019 IEEE 13th International Conference on ASIC (ASICON), 2019
As known to all, polar codes have been chosen as the control channel codes for the enhance mobile broadband (eMBB) scenario in the 3GPP RAN1. Due to its excellent performance, polar codes also have caused widespread concern in the academia and industry.
