Abstract

In this work, we provide first-in-class measurement results for fast-convolution-based filtered orthogonal frequencydivision multiplexing (FC-F-OFDM) processing implemented on a universal software radio peripheral (USRP) software-defined radio (SDR). The fast-convolution-based processing offers a highly efficient and flexible filtered OFDM scheme allowing to achieve high spectral utilization in different channel bandwidths. Through the SDR implementation and transmitter spectrum emission measurements, we show that FC-F-OFDM allows to increase spectrum utilization compared to the fifth generation new radio (5G NR) Release-15 requirements. Furthermore, considering the out-of-band emission masks and adjacent-channel-leakage-ratio requirements, FC-F-OFDM provides a larger interference margin than well-known windowed overlap-and-add OFDM processing.
