Improved Low-Density Parity-Check Codes for Burst Erasure Channels

  title={Improved Low-Density Parity-Check Codes for Burst Erasure Channels},
  author={Enrico Paolini and Marco Chiani},
  journal={2006 IEEE International Conference on Communications},
In this work we deal with Low-Density Parity-Check (LDPC) codes under iterative message passing decoding algorithm, over channels introducing bursts of erasures. The burst erasure channel model we consider in this paper can be seen as an erasure channel based on a hidden Markov chain (HMC-EC). In order to characterize the channel, in the first part of the paper the expression of mutual information is recalled for any erasure channel with memory and with i.i.d. and equiprobable input symbols.
