Layered Message Passing AlgorithmDynamic SchedulingRecently, LDPC plays a vital role in error floor performance near to Shannon limit. LDPC mainly suits, when length of the codeword is large, over the finite field. This paper presents parity check matrix of non-binary LDPC encoded innovatively ...
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 ...
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 ...
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...
We discuss and analyze a list-message-passing decoder with verification for low-density parity-check (LDPC) codes on the q-ary symmetric channel (q-SC). Ra... F Zhang,HD Pfister - 《IEEE Transactions on Information Theory》 被引量: 67发表: 2011年 The impact of causality on information-...
A powerful Forward Error Correction (FEC) subsystem is needed in almost all wireless communication systems. Low-Density Parity-Check (LDPC) codes are ...
In one embodiment, an electronic system includes a decoder configured to decode an encoded data unit using multiple variable nodes and multiple check nodes to perform a low-density parity check (LDPC) decoding process. The encoded data unit can be received from a solid-state memory array. As ...
While binary LDPC codes have shown great performance, nonbinary LDPC codes have empirically shown even better performance, especially for small codeword lengths. A configurable output synchronous FIFO is used to store the output for the next block. View Nonbinary LDPC Decoder full description to.....
