Design of Wideband Communication Waveform for Swarm UAV Warfare

Abstract

In order to improve the battlefield survivability and information reliability of swarm UAV (unmanned aerial vehicle) data link network, the signal waveform was redesigned in signal time domain and frequency, combining with symbol interleave and LDPC encoding. The physical layer design of the terminal machine was optimized, the collision probability of the signal was reduced, and the transmission time delay of time-sensitive information was reduced.
