摘要

Due to the properties of high speed and high dynamics in aeronautic channels, different modulations turn out to be different performance. Especially, the differential modulation can be utilized to handle the frequency offset caused by he Doppler effect with simple schemes. However, so far, the systematic BER performance evaluation in aeronautic channels has not been reported. This paper undertakes the performance evaluation and comparison of different phase shift keying modulation schemes in aeronautic channels. Specifically, BER curves and outage probabilities of various modulation schemes in high dynamic environments are investigated. As the conclusion, the differential modulation schemes are more suitable for aeronautic channels in order to withstand the Doppler shift and the changing rate of the Doppler.
