Transmission Schemes for Gaussian Interference Channels with Transmitter Processing Energy
Xi Liu, Elza Erkip
This work considers communication over Gaussian interference channels with processing energy cost, which explicitly takes into account the energy expended for processing when trans…
Lossy Computing of Correlated Sources with Fractional Sampling
Xi Liu, Osvaldo Simeone, Elza Erkip
This paper considers the problem of lossy compression for the computation of a function of two correlated sources, both of which are observed at the encoder. Due to presence of obs…
Energy-Efficient Sensing and Communication of Parallel Gaussian Sources
Xi Liu, Osvaldo Simeone, Elza Erkip
Energy efficiency is a key requirement in the design of wireless sensor networks. While most theoretical studies only account for the energy requirements of communication, the sens…
On the Gaussian Z-Interference Channel with Processing Energy Cost
Xi Liu, Elza Erkip
This work considers a Gaussian interference channel with processing energy cost, which explicitly takes into account the energy expended for processing when each transmitter is on.…
A Secure Communication Game with a Relay Helping the Eavesdropper
Melda Yuksel, Xi Liu, Elza Erkip
In this work a four terminal complex Gaussian network composed of a source, a destination, an eavesdropper and a jammer relay is studied under two different set of assumptions: (i)…
A Game-Theoretic View of the Interference Channel: Impact of Coordination and Bargaining
Xi Liu, Elza Erkip
This work considers coordination and bargaining between two selfish users over a Gaussian interference channel. The usual information theoretic approach assumes full cooperation am…
