Frequency domain equalization of MSK for UAV data link

In this paper, confronting the frequency-selective fading in the channel of unmanned aerial vehicle (UAV), the technology of single-carrier frequency domain equalization (SCFDE) which can resist to the frequency selective fading is discussed for minimum shift keying (MSK). And then, a channel model is discussed for UAV and the composition of the UAV communication channel is analyzed. What´s more, the impulse response model of the channel is given similar to the Rice channel. In the end, simulation of SCFDE in the channel model under three scenarios shows that SCFDE is an effective approach resistance to the frequency selective fading.
