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…
