通过分析认知无线(CR)物理层面临的安全问题,提出了动态跳频扩谱通信机制,并将跳频通信引入认知无线电体系,提高了认知无线电系统的安全性。
Dynamic Frequency - Hopping Spread Spectrum ( FHSS ) communication mechanism is proposed after analyzing the security problem on the congnitive radio (CR) physical layer, and HF communication is introduced into CR system to enhance the security of the CR system.
