Abstract

In this paper, an Unmanned Aerial Vehicle (UAV) fading channel is simulated on the basis of an analysis of the channel characteristics. A hybrid DS/FH spread spectrum communication system model is constructed, the system performance under the channel which presence both AWGN and partial-band interference is studied. Bit error rate performance is determined in the presence of both AWGN and various types of interference, and performance is compared to that of noncoherent FSK systems, and an improvement is achievable with hybrid spread spectrum system.
