摘要
根据随机微分与噪声信号处理的内在联系,对相位噪声信号进行了系统的分析。建立了相位噪声通过滤波器后所满足的福克尔普朗克方程,利用群移傅里叶变换(MGFT)给出了方程的解,得到了相位噪声幅度和相位的联合概率密度函数。
Abstract
According to the intrinsic relations between the stochastic differential and the phase noise signal processing, the phase noise is systematically analyzed. The Fokker-Planck equation of phase noise is presented. The solution is given by using the Motion-Group Fourier transform equation. The joint probability density function of phase noise in the filter is given.
