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...

AWGN Channel Analysis of Terminated LDPC Convolutional Codes
— It has previously been shown that ensembles of terminated protograph-based low-density parity-check (LDPC) convolutional codes have a typical minimum distance that grows linear...

Waterfilling: a connection between information theoretic and perceptually based watermarking
We present a hybrid approach to image watermarking that exploits results from both information theory and perceptual studies. Towards this purpose we use a waterfilling-type algor...

The Gaussian MAC with Conferencing Encoders
We derive the capacity region of the Gaussian version of Willems's two-user MAC with conferencing encoders. This setting differs from the classical MAC in that, prior to each ...

Exploiting Partial Cooperation for Source and Channel Coding in Sensor Networks
Abstract—A network with two sensors communicating a remote measurement to a common access point (AP) is investigated. The sensors are connected via out-of-band and finite-capaci...
