Symbol-Level GRAND for High-Order Modulation over Flat Fading Channels
Ioannis Chatzigeorgiou, Francisco A. Monteiro
Guessing random additive noise decoding (GRAND) is a noise-centric decoding method, which is suitable for ultra-reliable low-latency communications, as it supports high-rate error…
Spark Optimization of Linear Codes for Reliable Data Delivery by Relay Drones
Ioannis Chatzigeorgiou
Data gathering operations in remote locations often rely on relay drones, which collect, store and deliver transmitted information to a ground control station. The probability of t…
Low Complexity Optimization of the Asymptotic Spectral Efficiency in Massive MIMO NOMA
Lucinda Hadley, Ioannis Chatzigeorgiou
Massive multiple-input multiple-output (MIMO) technology facilitates huge increases in the capacity of wireless channels, while non-orthogonal multiple access (NOMA) addresses the…
Power Efficient IRS-Assisted NOMA
Jianyue Zhu, Yongming Huang, Jiaheng Wang +2
In this paper, we propose a downlink multiple-input single-output (MISO) transmission scheme, which is assisted by an intelligent reflecting surface (IRS) consisting of a large num…
How Do Non-Ideal UAV Antennas Affect Air-to-Ground Communications?
M. G. Khoshkholgh, Keivan Navaie, Halim Yanikomeroglu +2
Analysis of the performance of Unmanned Aerial Vehicle (UAV)-enabled communications systems often relies upon idealized antenna characteristic, where the side-lobe gain of UAVs' an…
Caching or No Caching in Dense HetNets?
M. G. Khoshkholgh, Keivan Navaie, Kang G. Shin +2
Caching the content closer to the user equipments (UEs) in heterogenous cellular networks (HetNets) improves user-perceived Quality-of-Service (QoS) while lowering the operators ba…
