abstract = "In this paper, we proposed USFDMA waveform using LoS-MIMO in an UAV-based non-terrestrial network. Due to a spatio-frequency filter and a time-domain window, the USFDMA waveform has a reduced CP length even with sync errors of mobile users; therefore, the USFDMA achieves high spectral efficiency performance, compared to the conventional MIMO-OFDMA waveform."
