Secure Degrees of Freedom of One-hop Wireless Networks
Jianwei Xie, Sennur Ulukus
We study the secure degrees of freedom (d.o.f.) of one-hop wireless networks by considering four fundamental Gaussian network structures: wiretap channel, broadcast channel with co…
An Outer Bound for the Vector Gaussian CEO Problem
Ersen Ekrem, Sennur Ulukus
We study the vector Gaussian CEO problem, where there are an arbitrary number of agents each having a noisy observation of a vector Gaussian source. The goal of the agents is to de…
Optimal Sum-Rate of the Vector Gaussian CEO Problem
Ersen Ekrem, Sennur Ulukus
This document is withdrawn due to an error in Lemma 4.
AWGN Channel under Time-Varying Amplitude Constraints with Causal Information at the Transmitter
Omur Ozel, Sennur Ulukus
We consider the classical AWGN channel where the channel input is constrained to an amplitude constraint that stochastically varies at each channel use, independent of the message.…
