摘要
文章介绍Wigner-Ville分布在时频分析中的应用,基于Wigner-Ville分布的特点,给出了Wigner-Ville分布在ADSP21160平台上的软件仿真实现。仿真结果表明:信号的WVD处理适合于非平稳的线性调频信号,可以通过信号的WVD分布来估计信号的瞬时频率。
This paper first introduces Wigner- Ville distribution and its application in time- Frequency Analysis, and the simulation result of WVD is implemented by ADSP21160 based on its property, The simulation result shows that Wigner- ViUe distribution of signal can be used to estimate the instantaneous frequency of signal because of its suitability for non - stationary linear frequency - modulated signal.
