Secure Degrees of Freedom of K-User Gaussian Interference Channels: A Unified View
Jianwei Xie, Sennur Ulukus
We determine the exact sum secure degrees of freedom (d.o.f.) of the K-user Gaussian interference channel. We consider three different secrecy constraints: 1) K-user interference c…
Optimal Scheduling for Energy Harvesting Transmitters with Hybrid Energy Storage
Omur Ozel, Khurram Shahzad, Sennur Ulukus
We consider data transmission with an energy harvesting transmitter which has a hybrid energy storage unit composed of a perfectly efficient super-capacitor (SC) and an inefficient…
Energy Cooperation in Energy Harvesting Communications
Berk Gurakan, Omur Ozel, Jing Yang +1
In energy harvesting communications, users transmit messages using energy harvested from nature during the course of communication. With an optimum transmit policy, the performance…
Secure Degrees of Freedom of the Gaussian Wiretap Channel with Helpers and No Eavesdropper CSI: Blind Cooperative Jamming
Jianwei Xie, Sennur Ulukus
We consider the Gaussian wiretap channel with M helpers, where no eavesdropper channel state information (CSI) is available at the legitimate entities. The exact secure d.o.f. of t…
