Study on coverage of airborne ultrashort wave communication under normal white noise interference

摘要

Using ITU-R P.1546 model for propagation loss prediction of airborne ultrashort wave communication. On this basis, we give the calculation formula of signal to interference ratio of the ultrashort wave communication receiver when the enemy using Gaussian white noise for repressive interference. We also give the calculation method of the bit error rate of the digital communication system when it's under different modulation and demodulation modes. The coverage of analog signal when it's under different jammer power and different jammer-receiver distance is simulated and analyzed. We also analyze the coverage of digital signal when it's under different modulation and demodulation modes. This paper also analyzes the optimal anti-jamming modulation and demodulation methods for airborne ultrashort wave digital communication under Gaussian white noise repressive interference condition.
