Mutual Information-Maximizing Quantized Belief Propagation Decoding of Regular LDPC Codes [PDF]

, 2022
In this paper, we propose a class of finite alphabet iterative decoder (FAID), called mutual information-maximizing quantized belief propagation (MIM-QBP) decoder, for decoding regular low-density parity-check (LDPC) codes.

A Low-Complexity Belief Propagation Based Decoding Scheme for Polar Codes - Decodability Detection and Early Stopping Prediction

IEEE Access, 2019
In the 5G communication systems, polar code has been adapted as the control channel coding solution in the enhanced mobile broadband (eMBB) scenario. Although different decoding schemes, including belief propagation (BP) and successive cancellation (SC ...

Belief propagation vs. TAP for decoding corrupted messages [PDF]

, 1998
We employ two different methods, based on belief propagation and TAP,for decoding corrupted messages encoded by employing Sourlas's method, where the code word comprises products of K bits selected randomly from the original message.

Anti-Cycle-Slip LDPC Decoding Algorithm for BPSK System

Dianxin kexue, 2014
When cycle-slip occurs in BPSK modulation system, sign of information sequence which is input of LDPC decoder is opposite to the original one. This problem will lead to decoder failure.

Consensus and Return Residual Belief Propagation for Low-Latency LDPC Decoding

IEEE Access
We propose two new decoding algorithms for low-density parity-check (LDPC) codes. The Consensus and Return residual belief propagation (C&R-RBP) algorithm reduces the number of iterations required to achieve a target decoding error rate over an AWGN ...
