UAV Sound Acquisition System Design and its Applications
The use of unmanned aerial vehicles (UAV) has seen increasing influence in recent years. A number of UAV-embedded tools have been developed using visual sensing, while audio based sensing from UAVs has received much less ... -
UAV-derived greenness and within-crown spatial patterning can detect ash dieback in individual trees
(2024-04-01)Ash Dieback (ADB) has been present in the UK since 2012 and is expected to kill up to 80% of UK ash trees. Detecting and quantifying the extent of ADB in individual tree crowns (ITCs), which is crucial to understanding ... -
UAV-Enabled Multi-Pair Massive MIMO-NOMA Relay Systems With Low-Resolution ADCs/DACs
(IEEE, 2023-09-14)In this article, we consider an unmanned aerial vehicle (UAV)-enabled massive multiple-input multiple-out (MIMO) non-orthogonal multiple access (NOMA) full-duplex (FD) two-way relay (TWR) system with low-resolution ... -
