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…
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.…
