Performance analysis of Differential Frequency Hopping Communication system over Rician channel

摘要

As Unmanned Aerial Vehicle (UAV) play a progressively important role in both military and civilian affairs, the requirements on its dependability and validity are higher and higher. In order to meet the application requirements of the UAV downlink communication system, we did the theoretical research and analysis based on the basic principles of transmission and reception of differential frequency hopping (DFH) communication systems. In this paper, for a case where the sampling frequency, hopping speed, frequency hopping bandwidth, and frequency hopping points is constant, a theoretical study about the performance analysis of the differential hopping communication systems over Rician fading channels with different fan-out coefficients, full-band jamming, partial-band jamming, and comb spectrum jamming is confirmed. On the whole, the larger the fan-out coefficient, the stronger the anti-jamming comprehensiveness of the differential frequency hopping communication system.
