Variations on Information Embedding in Multiple Access and Broadcast Channels
ShivaPrasad Kotagiri, J. Nicholas Laneman
Information embedding (IE) is the transmission of information within a host signal subject to a distortion constraint. There are two types of embedding methods, namely irreversible…
Outage-Efficient Downlink Transmission Without Transmit Channel State Information
Wenyi Zhang, Shivaprasad Kotagiri, J. Nicholas Laneman
This paper investigates downlink transmission over a quasi-static fading Gaussian broadcast channel (BC), to model delay-sensitive applications over slowly time-varying fading chan…
Cooperative Relaying with State Available at the Relay
Abdellatif Zaidi, Shivaprasad Kotagiri, J. Nicholas Laneman +1
We consider a state-dependent full-duplex relay channel with the state of the channel non-causally available at only the relay. In the framework of cooperative wireless networks, s…
Writing on Dirty Paper with Resizing and its Application to Quasi-Static Fading Broadcast Channels
Wenyi Zhang, Shivaprasad Kotagiri, J. Nicholas Laneman
This paper studies a variant of the classical problem of ``writing on dirty paper'' in which the sum of the input and the interference, or dirt, is multiplied by a random variable…
