Chaos Value Exerting an Influence on Phase Noise Measurement

Pages: 18-21

Journal: MEASUREMENT & CONTROL TECHNOLOGY

Keyword:  混沌Lyapunov指数鉴相测量法相位噪声;
Abstract: 针对在相位噪声测量过程中,存在测得的振荡器相位噪声比实际中使用时的相位噪声要好一些的问题,考虑到非线性系统中,混沌现象的普遍存在,提出修正振荡器的输出表达式,使其中含有弱混沌分量.采用常用的鉴相测量法,通过仿真得出混沌分量对振荡器相位噪声测量的影响结果.讨论了为减小混沌信号时振荡器相位噪声的影响所需研究的一些问题.
