“…BPSK and QPSK devices are simple and anti-noise. 8PSK and 16PSK have high spectrum utilization and are good at transmission, but their signal is weaker and their noise immunity is weak [18]. At the same time, since the principle of PSK modulation and demodulation is basically similar, the BPSK modulation and demodulation principle with the best anti-noise performance and strong adaptability to nonlinear channels and fading channels [19] is analysed in this section.…”

UAVs have many functions in detection, fire protection, communication, etc. in modern life, but the complex electromagnetic environment has a very bad impact on the UAV communication link. In this paper, the BPSK modulation and demodulation method of the UAV downlink communication link was analysed. Some typical electromagnetic pulse models were established, including sinusoidal pulse, square wave pulse, triangular wave pulse, Gaussian noise, electric fast transient pulse and surge pulse. The amplitude of different electromagnetic pulses was analysed when UAV communication error rate achieve 5%. Furthermore, the influence on the transmission image quality via UAV downlink was analysed with different electromagnetic pulses, which will provide a theoretical basis for the anti-interference optimization design of UAV communication links in the future.
