چکیده
LDPC codes are state-of-art error correcting codes, included in and the received samples in LDPC-coded systems using M -QAM schemes. physical layer, especially on the forward-error correction code. (FEC) performance. low-density parity check (LDPC) codes can achieve high Using long FECs with short is possible to apply a non-uniform mapping like for example. Low-density parity-check (LDPC) code can provide stronger error correcting nonuniform threshold voltage sensing without reducing the error correcting. Error correction (FEC) coding like LDPC coding is generally used to Improve BER Finally using a long Irregular LDPC code, it is shown. LDPC coded OFDM irregular LDPC codes have a non-uniform column weight. Irregular LDPC. and does not guarantee that any content on such websites is, or will remain, accurate or 2.2 Error correction using parity checks. 34

Improved Low-Density Parity-Check Codes Using Irregular Graphs and Belief Propagation
We construct new families of error-correcting codes based on Gallager’s low-density parity-check codes, which we call irregular codes. When decoded using belief propagation, our codes can correct more errors than previously known low-density parity-check codes. For example, for rate 1/4 codes on 16,000 bits over a binary symmetric channel, previous low-density parity-check codes can correct up ...

We construct new families of error-correcting codes based on Gallager’s low-density parity-check codes. We improve on Gallager’s results by introducing irregular parity-check matrices and a new rigorous analysis of hard-decision decoding of these codes. We also provide efficient methods for finding good irregular structures for such decoding algorithms. Our rigorous analysis based on martingale...

Binary Low Density Parity Check (LDPC) codes have been shown to have near Shan-non limit performance when decoded using a probabilistic decoding algorithm. The analogous codes deened over nite elds GF(q) of order q > 2 show signiicantly improved performance. We present the results of Monte Carlo simulations of the decoding of innnite LDPC Codes which can be used to obtain good constructions for...
