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。 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.
