A G Function Algorithm Based on Chaos Mapping

在跳频通信中,G函数的性能直接影响着差分跳频信号的性能。文章在研究传统G函数构造方法的基础上,给出了一种新的基于混沌映射的G函数构造方法,该方法具有结构简单、便于控制的优点。通过仿真证明了所构造的G函数具有良好的随机性和均匀性,它对提高差分跳频信号的性能有着重要意义。

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.
