Modified belief-propagation algorithm for decoding of irregular low-density parity-check codes

, 2002
A modified belief-propagation algorithm is proposed for decoding of irregular low-density parity-check codes. This algorithm effectively reduces the decoding complexity while achieving a BER performance near to or even better than that of the standard ...

BlockBP decoder for the surface code

Physical Review Research
We present a new decoder for the surface code, which combines the accuracy of the tensor-network decoders with the efficiency and parallelism of the belief-propagation algorithm.

Belief Propagation Decoding for Short-Length Codes Based on Sparse Tanner Graph

IEEE Communications Letters
In this letter, we present a novel approach to improve belief propagation (BP) decoding performance by sparsifying the Tanner graph. Our proposed method first constructs a low-weight parity-check (LWPC) matrix with increased rows based on the original ...

Belief propagation decoding of polar codes on permuted factor graphs [PDF]

IEEE Wireless Communications and Networking Conference, 2018
We show that the performance of iterative belief propagation (BP) decoding of polar codes can be enhanced by decoding over different carefully chosen factor graph realizations.

Belief Propagation With Permutated Graphs of Polar Codes

IEEE Access, 2020
The belief propagation (BP) decoding of polar codes provides better bit error rate (BER) and packet error rate (PER) performance than the successive cancelation (SC) decoding.

A Reliability Profile Based Low-Complexity Dynamic Schedule LDPC Decoding

IEEE Access, 2022
In order to improve the Bit Error Rate (BER) performance of Low-Density Parity-Check (LDPC) codes, In this paper, we propose a Reliability Profile (RP) Based Low-Complexity Dynamic Schedule, called RPD.

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.

CRC-Aided Adaptive BP Decoding of PAC Codes

Entropy, 2022
Although long polar codes with successive cancellation decoding can asymptotically achieve channel capacity, the performance of short blocklength polar codes is far from optimal.
