ROBUST UAV DOWNLINK VIA WIRELESS COMMUNICATION

Ensuring stable data transmission for unmanned aerial vehicles (UAVs) is crucial for their efficient here operation. Downlink communication, the transfer of information from the UAV to a ground station, can be hampered by various factors such as proximity, interference, and restricted capacity. To overcome these challenges, researchers are explorin

Radar altimetry provides a powerful tool for generating high-resolution terrain data. 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 accuracy of these measurements
