Data-oriented Coordinated Uplink Transmission for Massive IoT System
Jyri Hämäläinen, Rui Dinis, Mehmet C. Ilter
Recently, the paradigm of massive ultra-reliable low-latency IoT communications (URLLC-IoT) has gained growing interest. Reliable delay-critical uplink transmission in IoT is a cha…
Index Modulation-based Information Harvesting for Far-Field RF Power Transfer
M. Ertug Pihtili, Mehmet C. Ilter, Ertugrul Basar +2
While wireless information transmission (WIT) is evolving into its sixth generation (6G), maintaining terminal operations that rely on limited battery capacities has become one of…
UAV-based Maritime Communications: Relaying to Enhance the Link Quality
Abdullah Taha Çağan, Görkem Berkay Koç, Handan Yakın +5
Providing a stable connectivity in maritime communications is of utmost importance to unleash the full potential of smart ports. Nonetheless, due to the crowded nature of harbor en…
A canonical correlation-based framework for performance analysis of radio access networks
Furqan Ahmed, Muhammad Zeeshan Asghar, Jyri Hämäläinen
Data driven optimization and machine learning based performance diagnostics of radio access networks entails significant challenges arising not only from the nature of underlying d…
Resource Allocation in a Quantum Key Distribution Network with LEO and GEO trusted-repeaters
Milo Grillo, Alexis A. Dowhuszko, Mohammad-Ali Khalighi +1
Quantum Key Distribution~(QKD) is a technology that enables the exchange of private encryption keys between two legitimate parties, using protocols that involve quantum mechanics p…
Visible light communication-based monitoring for indoor environments using unsupervised learning
Mehmet C. Ilter, Alexis A. Dowhuszko, Jyri Hämäläinen +1
Visible Light Communication~(VLC) systems provide not only illumination and data communication, but also indoor monitoring services if the effect that different events create on th…
Doppler Spectrum Analysis of a Roadside Scatterer Model for Vehicle-to-Vehicle Channels: An Indirect Method
Sangjo Yoo, David González G., Jyri Hämäläinen +1
In vehicle-to-vehicle (V2V) channels, such roadside scatterers (RSSs) as houses, buildings, trees, and many more, play a crucial role in the determination of the Doppler power spec…
Spatial Mappings for Planning and Optimization of Cellular Networks
David González G., Harri Hakula, Antti Rasila +1
In cellular networks, users are grouped into different cells and served by different access points (base stations) that provide wireless access to services and applications. In gen…
Asymptotic Analysis of Multi-Antenna Cognitive Radio Systems Using Extreme Value Theory
Ruifeng Duan, Zhong Zheng, Riku Jäntti +1
We consider a spectrum-sharing cognitive radio system with antenna selection applied at the secondary transmitter (ST). Based on the extreme value theory, we deduce a simple and ac…
Looking at Cellular Networks Through Canonical Domains and Conformal Mapping
David González G., Jyri Hämäläinen
In order to cope with the rapidly increasing service demand in cellular networks, more cells are needed with better resource usage efficiency. This poses challenges for the network…
Outage Capacity of Rayleigh Product Channels: a Free Probability Approach
Zhong Zheng, Lu Wei, Roland Speicher +3
The Rayleigh product channel model is useful in capturing the performance degradation due to rank deficiency of MIMO channels. In this paper, such a performance degradation is inve…
