Empirical Low-Altitude Air-to-Ground Spatial Channel Characterization for Cellular Networks Connectivity
Xuesong Cai, Tomasz Izydorczyk, José Rodríguez-Piñeiro +4
Cellular-connected unmanned aerial vehicles (UAVs) have recently attracted a surge of interest in both academia and industry. Understanding the air-to-ground (A2G) propagation chan…
Dynamic mmWave Channel Emulation in a Cost-Effective MPAC with Dominant-Cluster Concept
Xuesong Cai, Yang Miao, Jinxing Li +3
Millimeter-Wave (mmWave) massive multiple-input multiple-output (MIMO) has been considered as a key enabler for the fifth-generation (5G) communications. It is essential to design…
A Centralized and Scalable Uplink Power Control Algorithm in Low SINR Scenarios
Xuesong Cai, István Kovács, Jeroen Wigard +1
Power control is becoming increasingly essential for the fifth-generation (5G) and beyond systems. An example use-case, among others, is the unmanned-aerial-vehicle (UAV) communica…
Air-to-Ground Channel Characterization for Low-Height UAVs in Realistic Network Deployments
José Rodríguez-Piñeiro, Tomás Domínguez-Bolaño, Xuesong Cai +2
Due to the decrease in cost, size and weight, \acp{UAV} are becoming more and more popular for general-purpose civil and commercial applications. Provision of communication service…
Distributed Receivers for Extra-Large Scale MIMO Arrays: A Message Passing Approach
Abolfazl Amiri, Sajad Rezaie, Carles Navarro Manchon +1
We study the design of receivers in extra-large scale MIMO (XL-MIMO) systems, i.e. systems in which the base station is equipped with an antenna array of extremely large dimensions…
Joint Modeling of Received Power, Mean Delay, and Delay Spread for Wideband Radio Channels
Ayush Bharti, Ramoni Adeogun, Xuesong Cai +4
We propose a multivariate log-normal distribution to jointly model received power, mean delay, and root mean square (rms) delay spread of wideband radio channels, referred to as th…
Privacy-Preserving Distributed Optimization via Subspace Perturbation: A General Framework
Qiongxiu Li, Richard Heusdens, Mads Græsbøll Christensen
As the modern world becomes increasingly digitized and interconnected, distributed signal processing has proven to be effective in processing its large volume of data. However, a m…
Deep Learning Based Spatial User Mapping on Extra Large MIMO Arrays
Abolfazl Amiri, Carles Navarro Manch'on, Elisabeth de Carvalho
In an extra-large scale MIMO (XL-MIMO) system, the antenna arrays have a large physical size that goes beyond the dimensions in traditional MIMO systems. Because of this large dime…
Achieving Fair Random Access Performance in Massive MIMO Crowded Machine-Type Networks
José Carlos Marinello, Taufik Abrão, Richard Demo Souza +2
The use of massive multiple-input multiple-output (MIMO) to serve a crowd of user equipments (UEs) is challenged by the deficit of pilots. Assuming that the UEs are intermittently…
