Abstract

Abstract:

Link16 data link has a wide range of applications. Because of the application of spread spectrum hopping and coding technology, it has a strong anti-interference ability. In order to explore the response of Link16 data link in fading channel, based on additive white Gaussian noise channel, the system performance of Link16 data link through Nakagami-m fading channel is studied. The bit error rate (BER) expression of Link16 data link monopulse structure passing through Nakagami-m fading channel under multi-tone interference is derived, and the BER formula of double pulse structure is given. Simulation results verify the accuracy of BER formula of Link16 data link monpulse structure passing through Nakagami-m fading channel under multi-tone interference, analyze the influence of multi-path parameters on the anti-jamming performance of Link16 data link, and conclude that adding fading parameter m and discernible path can improve the system performance of Link16 data link. And when the signal-to-jamming ratio is constant and the number of interfered frequency points is 25 or more, the BER of the system reaches 10^-1.

Key words: Link16 data link, Nakagami-m fading channel, multi-tone interference, bit error rate (BER)
