Distributed joint source-channel arithmetic coding
We deal with the problem of distributed source coding with decoder side information, when the decoder observes the source through a noisy channel. Existing approaches employ syndr...

Image quantization under spatial smoothness constraints
Quantization, defined as the act of attributing a finite number of grey-levels to an image, is an essential task in image acquisition and coding. It is also intricately linked to ...

Algebraic Constructions of Graph-Based Nested Codes from Protographs
Nested codes have been employed in a large number of communication applications as a specific case of superposition codes, for example to implement binning schemes in the presence ...

PD+ attitude control of rigid bodies with improved performance
Abstract-- We address the problem of state feedback attitude control of a rigid body in quaternion coordinate space through a modified PD+ tracking controller. The control law ensu...
