Multi-resolution Source Coding Using Entropy Constrained Dithered Scalar Quantization
In this paper, we build multi-resolution source codes using entropy constrained dithered scalar quantizers. We demonstrate that for n-dimensional random vectors, dithering followe...

Codecell Contiguity in Optimal Fixed-Rate and Entropy-Constrained Network Scalar Quantizers
We consider the properties of optimal xed-rate and entropy-constrained scalar quantizers for nite alphabet sources. In particular, w econsider conditions under which the optimal s...

Multiple-Description Coding by Dithered Delta-Sigma Quantization
We address the connection between the multiple-description (MD) problem and Delta-Sigma quantization. The inherent redundancy due to oversampling in Delta-Sigma quantization, and ...

An Optimal Non-Uniform Scalar Quantizer for Distributed Video Coding
In this paper, we propose a novel algorithm to design an optimal non-uniform scalar quantizer for distributed video coding, which aims at achieving a coding rate close to joint co...

Simple coding for achieving mean square stability over bit-rate limited channels
The problem of characterizing lower bounds on data-rates needed for closed loop stability has been solved in a variety of settings. However, the available results lead to coding s...
