Performance Lower Bounds for Existing and New Uncoded Digital Watermarking Modulation Techniques
Abstract. Many coded digital watermarking systems development requires first the selection of a (uncoded) modulation technique to be part of a coded architecture. Therefore, perfo...

To Feed or Not to Feed Back
We study the communication over Finite State Channels (FSCs), where the encoder and the decoder can control the availability or the quality of the noise-free feedback. Specificall...

The Gateway Channel: Outage Analysis
— We consider a relay that simultaneously assists multiple source-destination pairs that do not have a direct link, the so-called gateway channel, and explore the sum capacity of...

A Reversible Watermarking Scheme for JPEG-2000 Compressed Images
In this paper, we present a novel reversible watermarking scheme for image authentication for JPEG/JPEG-2000 coded images. Since the watermarking scheme is reversible, the exact o...
