The decoding of Low Density Parity Check (LDPC) codes through the iterative process of belief propagation presents practical challenges for designers looking for real time performance in communication systems. Due to the geometric and finite pattern nature endemic in the construction of LDPC codes, this paper proposes the use of Multi Layer Perception (MLP) feed forward artificial neural networks to replace belief propagation to achieve constant decoding times while retaining performance levels comparable to more traditional decoding methods. Due to the back propagation training method used for neural networks, and the requirement of showing the network every possible input output sequence it will ever see, this paper also presents a novel method of approaching long block length codes far larger than is otherwise possible to train neural networks for with modern computer hardware.

PBP
DL : 0
用 LDPC 解码法,对原始信号通道的噪声进行评估,消去。具体原理可参照IEEE TCOM的论文。-Channel Noise Estimation or correlation estimation for distributed source coding Using Particle based Belief Propagation for LDPC decoding in AWGN and BSC models. This code is partially based on our published journal papers with some additional improvements. In this code, we removed the parameter \lambda to reduce the number of free parameters. PBP estimator is distributed in the hope that is will be useful, but without any warranty. The codes have not been optimized, so the estimation speed may be slow. To use PBP estimator source code in your research, please cite our journal papers published in IEEE TCOM.

New-Iterative-Decoding-Algorithms-for-Low-Density
DL : 0
Low-Density Parity-Check (LDPC) codes have gained lots of popularity due to their capacity achieving/approaching property. This work studies the iterative decoding also known as message-passing algorithms applied to LDPC codes. Belief propagation (BP) algorithm and its approximations, most notably min-sum (MS), are popular iterative decoding algorithms used for LDPC and turbo codes. The thesis is divided in two parts. In the rst part, a low-complexity binary message-passing algorithm derived the dynamic of analog decoders is presented and thoroughly studied. In the second part, a modication for improving the performance of BP and MS algorithms is proposed. It uses adaptive normalization of variable node message-Low-Density Parity-Check (LDPC) codes have gained lots of popularity due to their capacity achieving/approaching property.
