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This document is withdrawn due to an error in Lemma 4.
Secure Lossy Transmission of Vector Gaussian Sources
Ersen Ekrem, Sennur Ulukus
We study the secure lossy transmission of a vector Gaussian source to a legitimate user in the presence of an eavesdropper, where both the legitimate user and the eavesdropper have…
Degrees of Freedom Region of the Gaussian MIMO Broadcast Channel with Common and Private Messages
Ersen Ekrem, Sennur Ulukus
We consider the Gaussian multiple-input multiple-output (MIMO) broadcast channel with common and private messages. We obtain the degrees of freedom (DoF) region of this channel. We…
Capacity-Equivocation Region of the Gaussian MIMO Wiretap Channel
Ersen Ekrem, Sennur Ulukus
We study the Gaussian multiple-input multiple-output (MIMO) wiretap channel, which consists of a transmitter, a legitimate user, and an eavesdropper. In this channel, the transmitt…
Capacity Region of Gaussian MIMO Broadcast Channels with Common and Confidential Messages
Ersen Ekrem, Sennur Ulukus
We study the two-user Gaussian multiple-input multiple-output (MIMO) broadcast channel with common and confidential messages. In this channel, the transmitter sends a common messag…
