On Construction of Moderate-Length LDPC Codes over Correlated Erasure Channels
The design of moderate-length erasure correcting low-density parity-check (LDPC) codes over correlated erasure channels is considered. Although the asymptotic LDPC code design rema...

Universal Lossless Compression of Erased Symbols
A source XXX goes through an erasure channel whose output is ZZZ. The goal is to compress losslessly XXX when the compressor knows XXX and ZZZ and the decompressor knows ZZZ. We pr...

Low-Complexity LDPC Codes with Near-Optimum Performance over the BEC
Recent works showed how low-density parity-check (LDPC) erasure correcting codes, under maximum likelihood (ML) decoding, are capable of tightly approaching the performance of an i...

Joint iterative decoding of LDPC codes for channels with memory and erasure noise
This paper investigates the joint iterative decoding of low-density parity-check (LDPC) codes and channels with memory. Sequences of irregular LDPC codes are presented that achieve...

Coding over an Erasure Channel with a Large Alphabet Size
An erasure channel with a fixed alphabet size q, where q 1, is studied . It is proved that over any erasure channel (with or without memory), Maximum Distance Separable (MDS) codes...

Frame based multiple description image coding in the wavelet domain
Multiple description codes generated by quantized frame expansions have been shown to perform well on erasure channels when compared to traditional channel codes. In this paper we...
