Surface-from-Gradients without Discrete Integrability Enforcement: A Gaussian Kernel Approach
—Representative surface reconstruction algorithms taking a gradient field as input enforces the integrability constraint in a discrete manner. While enforcing integrability allo...

The Rate Loss of Single-Letter Characterization: The "Dirty" Multiple Access Channel
For general memoryless systems, the typical information theoretic solution - when exists - has a "single-letter" form. This reflects the fact that optimum performance ca...

Energy efficient lossy transmission over sensor networks with feedback
The energy-distortion function (E(D)) for a network is defined as the minimum total energy required to achieve a target distortion D at the receiver without putting any restricti...

Distortion Exponents for Multi-Relay Cooperative Networks with Limited Feedback
— In this paper, we consider the transmission of a Gaussian source in a multi-relay cooperative network, where limited channel state feedback is combined with separate source and...
