| Abstract: | A scheme of satellite covert communication based on the coherent chaos shift keying signal is proposed in this paper,then the whole system model is also constructed.Then the hidden ability,anti-jamming performance and correct parameters selection of the system are analyzed through discrete baseband model.Theoretic analysis and simulation results indicate that the satellite covert communication based on coherent CSK signal has a better performance in hidden ability and anti-jamming,and thus provides a theore... |
