Wiretap Channels: Implications of the More Capable Condition and Cyclic Shift Symmetry
Omur Ozel, Sennur Ulukus
Characterization of the rate-equivocation region of a general wiretap channel involves two auxiliary random variables: U, for rate splitting and V, for channel prefixing. Evaluatio…
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…
Transmission with Energy Harvesting Nodes in Fading Wireless Channels: Optimal Policies
Omur Ozel, Kaya Tutuncuoglu, Jing Yang +2
Wireless systems comprised of rechargeable nodes have a significantly prolonged lifetime and are sustainable. A distinct characteristic of these systems is the fact that the nodes…
