Mobile Communications Beyond 52.6 GHz: Waveforms, Numerology, and Phase Noise Challenge
Toni Levanen, Oskari Tervo, Kari Pajukoski +2
In this article, the first considerations for the 5G New Radio (NR) physical layer evolution to support beyond 52.6GHz communications are provided. In addition, the performance of…
Aerial Access and Backhaul in mmWave B5G Systems: Performance Dynamics and Optimization
Nikita Tafintsev, Dmitri Moltchanov, Mikhail Gerasimenko +7
The use of unmanned aerial vehicle (UAV)-based communication in millimeter-wave (mmWave) frequencies to provide on-demand radio access is a promising approach to improve capacity a…
Wake-Up Radio based Access in 5G under Delay Constraints: Modeling and Optimization
Soheil Rostami, Sandra Lagen, Mario Costa +2
Recently, the concept of wake-up radio based access has been considered as an effective power saving mechanism for 5G mobile devices. In this article, the average power consumption…
PAPR Reduction with Mixed-Numerology OFDM
Selahattin Gökceli, Toni Levanen, Juha Yli-Kaakinen +3
High peak-to-average power ratio (PAPR) is a critical problem in orthogonal frequency-division multiplexing (OFDM). The fifth-generation New Radio (5G NR) facilitates the utilizati…
Full-Duplex OFDM Radar With LTE and 5G NR Waveforms: Challenges, Solutions, and Measurements
Carlos Baquero Barneto, Taneli Riihonen, Matias Turunen +5
This paper studies the processing principles, implementation challenges, and performance of OFDM-based radars, with particular focus on the fourth-generation Long-Term Evolution (L…
On Antenna Array Out-of-Band Emissions
Lauri Anttila, Alberto Brihuega, Mikko Valkama
We substantiate and extend recent research on the behavior of the out-of-band emissions in antenna array transmitters. Specifically, with multi-user precoding, we show that the emi…
