A G Function Algorithm Based on Chaos Mapping

In frequency hopping communication,the performance of G function affects the performance of differential frequency hopping signal directly.On the basis of studying the different from the traditional G function construction method,we present a new G function construction method based on chaotic mapping and which has the advantages of simple structure and can be controlled conveniently.The results of simulation prove that the constructed G function is more random and uniform.Therefore,it is useful to improve the performance of differential frequency hopping signal.
