Belief propagation decoding of Reed-Solomon codes: a bit-level soft decision decoding algorithm

, 2005
In this article we propose the application of Belief Propagation (BP) algorithm as a novel bit-level soft decision decoding (SDD) technique for Reed-Solomon (RS) codes. A brief tutorial on Belief Propagation algorithm is presented. A central issue in the

Adaptive Reweighted Freezing Belief Propagation Decoding for Polar Codes

Dianxin kexue
To address the challenges of high computational redundancy, slow convergence speed, and limited decoding performance in Belief Propagation (BP) decoding of polar codes, this paper proposes an Adaptive Reweighted Freezing (ARF) BP decoding algorithm. This

Effective BP-ORBGRAND Scheme for Short LDPC Codes

IEEE Access
Low-density parity-check (LDPC) codes have been widely used in practice due to their excellent error correction capabilities. However, the error correction performance of traditional decoding algorithms for LDPC codes is limited under short block lengths.

Low-Complexity Non-Binary LDPC and Modulation Schemes communicating over MIMO Channels

, 2004
In this contribution, Pearl’s belief propagation (BP) algorithm is invoked for constructing a belief network, which is employed for developing a joint detection aided transmit diversity scheme and a non-binary LDPC decoder constructed over a finite field

Enhanced belief propagation decoding of polar codes through concatenation

, 2014
The bit-channels of finite-length polar codes are not fully polarized, and a proportion of such bit-channels are neither completely 'noiseless' nor completely 'noisy'.

A Revolution: Belief Propagation in Graphs With Cycles

, 1998
Until recently, artificial intelligence researchers have frowned upon the application of probability propagation in Bayesian belief networks that have cycles. The probability propagation algorithm is only exact in networks that are cycle-free.
