المستخلص: Drone technology has evolved to become crucial in various fields. Vibrations and heat from external sources, as well as mechanical defects in design, can significantly impact the effectiveness of a drone's communication systems, thereby reducing their performance. This research uses the convolution neural network (CNN) technique and experiments and in a drone laboratory and simulation of theoretical model to look at how temperature and vibration affect two frequencies: the 2.4 GHz radio frequency and the 5.8 GHz radio frequency. The first step simulation of theoretical model and experiments were conducted in the drone laboratory, generating data that later served as input for artificial intelligence. The second step utilized a convolutional neural network (CNN) to regression the symbol error rate (SER), signal-to-noise ratio (SNR), and received signal strength indicator (RSSI). After creating the dataset in the first step, it was reprocessed and split into 70% training and 30% testing. Then, a graphical user interface (GUI) was created using MATLAB App Designer for user-friendly operation. The results showed that the drone communication system's performance declined as the vibration frequency, frequency carriers, and modulation order for M-QAM increased, primarily due to the influence of a vibrating antenna. Furthermore, the drone communication system's effectiveness decreased as the temperature increased.This research provides a valuable method for evaluating the efficiency of communication systems on unmanned aerial vehicle (UAV), which is particularly important for drone wireless system planning.
