Flexible fast-convolution processing for cellular radio evolution
Juha Yli-Kaakinen, Toni Levanen, Arto Palin +2
Orthogonal frequency-division multiplexing (OFDM) has been selected as a baseline waveform for long-term evolution (LTE) and fifth-generation new radio (5G NR). Fast-convolution (F…
Phase Noise Resilient Three-Level Continuous-Phase Modulation for DFT-Spread OFDM
Markku Renfors, Ismael Peruga Nasarre, Toni Levanen +2
A novel OFDM-based waveform with low peak-to-average power ratio (PAPR) and high robustness against phase noise (PN) is presented. It follows the discrete Fourier transform spread…
Joint Positioning and Tracking via NR Sidelink in 5G-Empowered Industrial IoT: Releasing the Potential of V2X Technology
Yi Lu, Mike Koivisto, Jukka Talvitie +4
The fifth generation (5G) mobile networks with enhanced connectivity and positioning capabilities play an increasingly important role in the development of automated vehicle-to-eve…
Frequency-Domain Signal Processing for Spectrally-Enhanced CP-OFDM Waveforms in 5G New Radio
Juha Yli-Kaakinen, AlaaEddin Loulou, Toni Levanen +4
Orthogonal frequency-division multiplexing (OFDM) has been selected as the basis for the fifth-generation new radio (5G-NR) waveform developments. However, effective signal process…
5G New Radio Evolution Towards Sub-THz Communications
Oskari Tervo, Toni Levanen, Kari Pajukoski +3
In this paper, the potential of extending 5G New Radio physical layer solutions to support communications in sub-THz frequencies is studied. More specifically, we introduce the sta…
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…
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…
Frequency-Selective PAPR Reduction for OFDM
Selahattin Gökceli, Toni Levanen, Taneli Riihonen +2
We study the peak-to-average power ratio (PAPR) problem in orthogonal frequency-division multiplexing (OFDM) systems. In conventional clipping and filtering based PAPR reduction te…
Transparent Tx and Rx Waveform Processing for 5G New Radio Mobile Communications
Toni Levanen, Juho Pirskanen, Kari Pajukoski +2
Several different waveform processing techniques have been studied and proposed for the 5G new radio (NR) physical layer, to support new mixed numerology and asynchronous services.…
