This MATLAB function encodes the input message, informationbits, using the LDPC matrix specified by the LDPC encoder configuration object, encodercfg.
LDPC decoding using one of these message-passing algorithms. Belief Propagation Decoding The implementation of the belief propagation algorithm is based on the decoding algorithm presented by Gallager [2]. For transmitted LDPC-encoded codewordc=c0,c1, …,cn-1, the input to the LDPC decoder is ...

The present disclosure relates generally to data decoding, and more particularly to non-binary iterative decoders. Non-binary LDPC codes and LDPC decoders that may be used to decode non-binary LDPC codes are disclosed. Systems and methods are also disclosed that compute messages related to non-...
For example, we implement an LDPC code designed for a binary symmetric channel (BSC). This design is not tuned to the fingerprint channel model. One possible improvement is to refine the design of the LDPC to match that channel. In general, however, while the “fingerprint channel” is a ...
Although various kinds of low complexity iterative decoding algorithms have been proposed, the FPGA implementation of NB-LDPC decoders still remains a big challenge due to its high complexity and long latency. Moreover, Prototype architecture of the NB-LDPC codes has been implemented by writing ...
For various order of Galois Field with different PCM structures, non-binary LDPC codes performances are analyzed. 展开 关键词: parity check matrix ECC NB-LDPC decoder IEEE 802.11 会议名称: International Conference on Communications & Signal Processing ...
This paper describes the implementation of a flexible combined binary and non-binary LDPC decoder. The ASIP architecture can be configured allowing re-use between both modes. Key in the architecture is parallelization, which is exploited in the SIMD engine. Binary LDPC codes intrinsically enables par...
The comm.LDPCDecoder System object uses the belief propagation algorithm to decode a binary LDPC code, which is input to the object as the soft-decision output (log-likelihood ratio of received bits) from demodulation.
The mpdecoder project provides an MATLAB class mpdecoder that allows doing message passing (MP) decoding of binary LDPC codes. The MATLAB class mpdecoder actually calls the C++ class MPDecoder through the MATLAB MEX interface, which ensures its high decoding speed. A standalone MATLAB LDPC ...
