RELIABLE UAV DOWNLINK VIA WIRELESS COMMUNICATION

Ensuring robust data transmission for unmanned aerial vehicles (UAVs) is crucial for their effective operation. Downlink communication, the transfer of data from the UAV to a ground station, can be hampered by various factors such as range, environmental conditions, and limited bandwidth. To overcome these challenges, researchers are exploring adva

Radar altimetry provides a powerful tool for acquiring high-resolution terrain data. By measuring 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 reliability of these measurements
