초록
When designing the waveform and channel for a wideband payload link to transfer UAV's mission data or video, dissimilarly to a narrow C2 link, the multipath propagation impact should be considered as well as time selectivity and large Doppler shift due to UAV high-velocity. For the wideband payload or control link, we propose two candidate waveforms, SC-FDMA with windowing and SC-FDE with RRC filtering, considering UAV channel and operation environments. The channel structure for the wideband link operation is also proposed, adopting the proposed waveform.
