Abstract :
To increase the scarcity of spectrum resources and enhance the anti-jamming performance of the system, a novel cognitive frequency hopping mechanism is proposed in the paper. It solves the problem that adaptive frequency hopping can´t distinguish between self-interference and interference from other wireless communication systems. The paper explains the mechanism of cognitive frequency hopping and presents simulation results of cognitive frequency hopping and adaptive frequency hopping under same conditions.
