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…
Generalized Fast-Convolution-based Filtered-OFDM: Techniques and Application to 5G New Radio
Juha Yli-Kaakinen, Toni Levanen, Arto Palin +2
This paper proposes a generalized model and methods for fast-convolution (FC)-based waveform generation and processing with specific applications to fifth generation new radio (5G-…
