RELIABLE UAV DOWNLINK VIA WIRELESS COMMUNICATION

Ensuring reliable data transmission for unmanned aerial vehicles (UAVs) is crucial for their successful operation. Downlink communication, the transfer of information from the UAV to a ground station, can be hampered by various factors such as range, environmental conditions, and low throughput. To overcome these challenges, researchers are explori

Radar altimetry provides a powerful tool for acquiring high-resolution terrain representations. By determining the time delay between transmitting and receiving radar signals, precise elevation measurements can be obtained. COFDM (Coded Orthogonal Frequency Division Multiplexing), a sophisticated modulation scheme, enhances the robustness of these
