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 challenged by various factors such as distance, environmental conditions, and low throughput. To overc

Radar altimetry provides a powerful tool for acquiring high-resolution terrain data. By determining the time click here delay between transmitting and receiving radar signals, precise elevation measurements can be obtained. COFDM (Coded Orthogonal Frequency Division Multiplexing), a sophisticated mo
