Ensuring robust data transmission for unmanned aerial vehicles (UAVs) is crucial for their effective operation. Downlink communication, the transfer of information from the UAV to a ground station, can be challenged by various factors such as distance, interference, and low throughput. To overcome these challenges, researchers are exploring innovat

Radar altimetry provides a powerful tool for generating high-resolution terrain maps. 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 measurement
