Load-Based On/Off Scheduling for Energy-Efficient Delay-Tolerant 5G Networks
Haluk Celebi, Yavuz Yapici, Ismail Guvenc +1
Dense deployment of small cells is seen as one of the major approaches for addressing the traffic demands in next-generation 5G wireless networks. The energy efficiency, however, b…
Low-Complexity Adaptive Beam and Channel Tracking for Mobile mmWave Communications
Yavuz Yapici, Ismail Guvenc
In this paper, we study low-complexity algorithms for beam and channel tracking for millimeter-wave (mmWave) communications. In particular, the least mean squares (LMS) and bidirec…
Enhancing Physical Layer Security for NOMA Transmission in mmWave Drone Networks
Nadisanka Rupasinghe, Yavuz Yapici, Ismail Guvenc +2
Physical layer security (PLS) is critically important for emerging wireless communication networks to maintain the confidentiality of the information of legitimate users. In this p…
Indoor Coverage Enhancement for mmWave Systems with Passive Reflectors: Measurements and Ray Tracing Simulations
Wahab Khawaja, Ozgur Ozdemir, Yavuz Yapici +3
The future 5G networks are expected to use millimeter wave (mmWave) frequency bands, mainly due to the availability of large unused spectrum. However, due to high path loss at mmWa…
Adaptive Detection of Structured Signals in Low-Rank Interference
Philip Schniter, Evan Byrne
In this paper, we consider the problem of detecting the presence (or absence) of an unknown but structured signal from the space-time outputs of an array under strong, non-white in…
Comparison of Limited Feedback Schemes for NOMA Transmission in mmWave Drone Networks
Nadisanka Rupasinghe, Yavuz Yapici, Ismail Guvenc +1
Introducing non-orthogonal multiple access (NOMA) transmission to an unmanned aerial vehicle (UAV) based communication network is a promising solution to enhance its spectral effic…
Coverage Enhancement for mmWave Communications using Passive Reflectors
Wahab Khawaja, Ozgur Ozdemir, Yavuz Yapici +2
Millimeter wave (mmWave) technology is expected to dominate the future 5G networks mainly due to large spectrum available at these frequencies. However, coverage deteriorates signi…
Non-Orthogonal Multiple Access for Mobile VLC Networks with Random Receiver Orientation
Yavuz Yapici, Ismail Guvenc
We consider a downlink multiuser visible light communications (VLC) network where users randomly change their location and vertical orientation. The non-orthogonal multiple access…
Non-Orthogonal Multiple Access for mmWave Drone Networks with Limited Feedback
Nadisanka Rupasinghe, Yavuz Yapici, Ismail Guvenc +1
Unmanned aerial vehicle (UAV) base stations (BSs) can be a promising solution to provide connectivity and quality of service (QoS) guarantees during temporary events and after disa…
