Polar Coding for Forward Error Correction in Space …
WebAFF3CT is an Open-source software (MIT license) dedicated to the Forward Error Correction (FEC or channel coding) simulations. It is written in C++11 and it supports a large range of codes: from the well-spread … WebKaiserslautern, Germany, Nov. 10, 2016 – Creonic GmbH today announced immediate availability of the new CCSDS AR4JA LDPC encoder and decoder IP core, following initial delivery to the first customer.The new core provides block length and code rate flexibility, complementing the field-proven CCSDS LDPC (8160, 7136) encoder and decoder IP core. In information theory, a low-density parity-check (LDPC) code is a linear error correcting code, a method of transmitting a message over a noisy transmission channel. An LDPC code is constructed using a sparse Tanner graph (subclass of the bipartite graph). LDPC codes are capacity-approaching codes, … See more Impractical to implement when first developed by Gallager in 1963, LDPC codes were forgotten until his work was rediscovered in 1996. Turbo codes, another class of capacity-approaching codes discovered … See more In 2003, an irregular repeat accumulate (IRA) style LDPC code beat six turbo codes to become the error-correcting code in the new See more Figure 1 illustrates the functional components of most LDPC encoders. During the encoding of a frame, the input data bits (D) are repeated and distributed to a set of … See more For large block sizes, LDPC codes are commonly constructed by first studying the behaviour of decoders. As the block size tends to infinity, … See more LDPC codes functionally are defined by a sparse parity-check matrix. This sparse matrix is often randomly generated, subject to the sparsity constraints—LDPC code construction is … See more As with other codes, the maximum likelihood decoding of an LDPC code on the binary symmetric channel is an NP-complete problem. Performing optimal decoding for a NP … See more LDPC codes can be compared with other powerful coding schemes, e.g. turbo codes. In one hand, BER performance of turbo codes is influenced … See more hardy hardy singapore
