Lossy Source Coding via Spatially Coupled LDGM Ensembles
Lossy Source Coding Spatially Coupled LDGM Ensembles
2012/2/27
We study a new encoding scheme for lossy source compression based on spatially coupled low-density generator-matrix codes. We develop a belief-propagation guided-decimation algorithm, and show that th...
Secure Lossy Source Coding with Side Information at the Decoders
Secure Lossy Source Coding Side Information Decoders
2010/12/9
This paper investigates the problem of secure lossy source coding in the presence of an eavesdropper with arbitrary correlated side informations at the legitimate decoder (referred to as Bob) and the ...
