초록
To design a wideband UAV link, we propose two candidate waveforms, SC-FDMA with windowing and SC-FDE with RRC filtering. Considering UAV channel and operation environments, a unified frame structure for both waveforms is also proposed. Based on the simulation results on transport block error on UAV multipath fading channels, we show that the performance of the two waveforms is similar. The wideband UAV link using SC-FDE-RRC is recommended in terms of coverage and spectrum shape.
