Cloud Radio Access Networks with Coded Caching
Yigit Ugur, Zohaib Hassan Awan, Aydin Sezgin
A cloud radio access network (C-RAN) is considered as a candidate to meet the expectations of higher data rate de- mands in wireless networks. In C-RAN, low energy base stations (B…
Individual Secrecy for the Broadcast Channel
Yanling Chen, O. Ozan Koyluoglu, Aydin Sezgin
This paper studies the problem of secure communication over broadcast channels under the individual secrecy constraints. That is, the transmitter wants to send two independent mess…
Interplay Between Delayed CSIT and Network Topology for Secure MISO BC
Zohaib Hassan Awan, Aydin Sezgin
We study the problem of secure transmission over a Gaussian two-user multi-input single-output (MISO) broadcast channel under the assumption that links connecting the transmitter t…
Cyclic Communication and the Inseparability of MIMO Multi-way Relay Channels
Anas Chaaban, Aydin Sezgin
The -user MIMO multi-way relay channel (Y-channel) consisting of users with antennas each and a common relay node with antennas is studied in this paper. Each user w…
Three-Way Channels with Multiple Unicast Sessions: Capacity Approximation via Network Transformation
Anas Chaaban, Henning Maier, Aydin Sezgin +1
A network of 3 nodes mutually communicating with each other is studied. This multi-way network is a suitable model for 3-user device-to-device communications. The main goal of this…
Full-Duplex vs. Half-Duplex Secret-Key Generation
Hendrik Vogt, Zohaib Hassan Awan, Aydin Sezgin
Full-duplex (FD) communication is regarded as a key technology in future 5G and Internet of Things (IoT) systems. In addition to high data rate constraints, the success of these sy…
