Regge trajectories for the heavy-light diquarks
Jiao-Kai Chen, Xia Feng, Jia-Qi Xie
We attempt to apply the Regge trajectory approach to the heavy-light diquarks composed of one heavy quark and one light quark. However, we find that the direct application of the u…
Secure Degrees of Freedom of Multi-user Networks: One-Time-Pads in the Air via Alignment
Jianwei Xie, Sennur Ulukus
We revisit the recent secure degrees of freedom (s.d.o.f.) results for one-hop multi-user wireless networks by considering three fundamental wireless network structures: Gaussian w…
Secure Degrees of Freedom of One-hop Wireless Networks with No Eavesdropper CSIT
Pritam Mukherjee, Jianwei Xie, Sennur Ulukus
We consider three channel models: the wiretap channel with helpers, the -user multiple access wiretap channel, and the -user interference channel with an external eavesdr…
Secure Degrees of Freedom Regions of Multiple Access and Interference Channels: The Polytope Structure
Jianwei Xie, Sennur Ulukus
The sum secure degrees of freedom (s.d.o.f.) of two fundamental multi-user network structures, the K-user Gaussian multiple access (MAC) wiretap channel and the K-user interference…
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…
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…
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…
