自适应跳频原理及其关键技术

自适应跳频技术是建立在自动信道质量分析基础上的自适应技术与跳频技术相结合的通信技术。采用该技术的通信双方在通信中自动适应信道变化,实时避开频率集中被干扰的频点,可提高通信的可靠性和抗干扰能力。文章在简述跳频通信基本原理的基础上,分析了自适应跳频通信的基本原理、抗干扰性能和通信过程,探讨了自适应跳频的实时信道质量分析、自适应跳频频率选择等关键技术,有助于对自适应跳频通信系统进行深入研究、分析和设计。

The Principles and Key Technologies of Adaptive Frequency Hopping

Technology of adaptive frequency hopping(AFH),based on automatic channel quality analysis,is a kind of communication technology combining adaptive technology with frequency hopping(FH) technology.Both sides who adopt this technology automatically adapt to changes of channel s state during communication,and at any time,avoid using those frequency points interfered to improve the reliability and antijamming capability of communication.Based on a brief introduction to the fundamental principle of FH communicat...
