Secure Communications for the Two-user Broadcast Channel with Random Traffic
Parthajit Mohapatra, Nikolaos Pappas, Jemin Lee +2
In this work, we study the stability region of the two-user broadcast channel (BC) with bursty data arrivals and security constraints. We consider the scenario, where one of the re…
Exploiting Trust Degree for Multiple-Antenna User Cooperation
Mingxiong Zhao, Jong Yeol Ryu, Jemin Lee +2
For a user cooperation system with multiple antennas, we consider a trust degree based cooperation techniques to explore the influence of the trustworthiness between users on the c…
Heterogeneous Cellular Networks with LoS and NLoS Transmissions--The Role of Massive MIMO and Small Cells
Qi Zhang, Howard H. Yang, Tony Q. S. Quek +1
We develop a framework for downlink heterogeneous cellular networks with line-of-sight (LoS) and non-line-of-sight (NLoS) transmissions. Using stochastic geometry, we derive tight…
