Trajectory Design for Energy Minimization in UAV-enabled Wireless Communications with Latency Constraints
Dinh-Hieu Tran, Thang X. Vu, Symeon Chatzinotas +2
This paper studies energy-efficient unmanned aerial vehicle (UAV)-enabled wireless communications, where the UAV acts as a flying base station (BS) to serve the ground users (GUs)…
On the Spectral and Energy Efficiencies of Full-Duplex Cell-Free Massive MIMO
Hieu V. Nguyen, Van-Dinh Nguyen, Octavia A. Dobre +4
In-band full-duplex (FD) operation is practically more suited for short-range communications such as WiFi and small-cell networks, due to its current practical limitations on the s…
Inexact Block Coordinate Descent Algorithms for Nonsmooth Nonconvex Optimization
Yang Yang, Marius Pesavento, Zhi-Quan Luo +1
In this paper, we propose an inexact block coordinate descent algorithm for large-scale nonsmooth nonconvex optimization problems. At each iteration, a particular block variable is…
A Bayesian Poisson-Gaussian Process Model for Popularity Learning in Edge-Caching Networks
Sajad Mehrizi, Anestis Tsakmalis, Symeon Chatzinotas +1
Edge-caching is recognized as an efficient technique for future cellular networks to improve network capacity and user-perceived quality of experience. To enhance the performance o…
A Joint Solution for Scheduling and Precoding in Multiuser MISO Downlink Channels
Ashok Bandi, Bhavani Shankar Mysore R, Symeon Chatzinotas +1
The long-term average performance of the MISO downlink channel, with a large number of users compared to transmit antennas of the BS, depends on the interference management which n…
