Toward a unified framework for modeling and analysis of diversity in joint source-channel coding
The study of Joint Source-Channel Coding (JSCC) systems faces one major challenge in obtaining an analytical expression for the function that links end-to-end distortion with chann...

Wyner-Ziv coding over broadcast channels: digital schemes
This paper addresses lossy transmission of a common source over a broadcast channel when there is correlated side information at the receivers. The quadratic Gaussian and binary H...

Source Requantization: Successive Degradation and Bit Stealing
We consider source requantization in two forms -- successive degradation (i.e., source fidelity reduction) and bit stealing (i.e., information embedding) -when no forward planning...

On the Systematic Measurement Matrix for Compressed Sensing in the Presence of Gross Errors
Inspired by syndrome source coding using linear error-correcting codes, we explore a new form of measurement matrix for compressed sensing. The proposed matrix is constructed in t...

Analog Matching of Colored Sources to Colored Channels
Analog (uncoded) transmission provides a simple scheme for communicating a Gaussian source over a Gaussian channel under the mean squared error (MSE) distortion measure. Unfortuna...
