Joint source coding, routing and power allocation in wireless sensor networks
This paper proposes a cross-layer optimization framework for the wireless sensor networks. In a wireless sensor network, each sensor makes a local observation of the underlying phy...

Source fidelity over fading channels: performance of erasure and scalable codes
We consider the transmission of a Gaussian source through a block fading channel. Assuming each block is decoded independently, the received distortion depends on the tradeoff betw...

Nested turbo codes for the Costa problem
Driven by applications in data-hiding, MIMO broadcast channel coding, precoding for interference cancellation, and transmitter cooperation in wireless networks, Costa coding has la...

On Transform Coding with Dithered Quantizers
This paper is concerned with optimal transform coding in conjunction with dithered quantization. While the optimal deterministic quantizer's error is uncorrelated with the re...

Diversity Embedded Streaming Erasure Codes (DE-SCo): Constructions and Optimality
Streaming erasure codes encode a source stream to guarantee that each source packet is recovered within a fixed delay at the receiver over a burst-erasure channel. This paper intro...
