We consider the ensemble of regular LDPC codes and use recent concentration results on the distance spectrum to derive upper bounds on the error exponent.

Mar 17, 2008 · Abstract: The error performance of the ensemble of typical LDPC codes transmitted over the binary erasure channel (BEC) is analyzed.

Mar 17, 2008 · Low-density parity-check (LDPC) codes, discovered by Gallager [1], have been widely researched over the last decade and a half.

Mar 3, 2022 · SUMMARY. In channel decoding, a decoder with suboptimal metrics may be used because of the uncertainty of the channel statistics or the.

This paper deals with the specific construction of binary low-density parity-check (LDPC) codes. We derive lower bounds on the error exponents for these codes.

In this paper, we derive the upper bound of the average block error probability of a given standard irregular LDPC code ensemble under the maximum ...

LDPC codes using upper bounds for a binary-input AWGN channel. The bounds are based on Gallager's upper bound on the ensemble distance spectrum of LDPC ...

Upper bounds on the undetected error probabilities of some expurgated ensembles of binary and regular (6,12) LDPC codes under the optimal and sub-optimal ...
