Tomographic and entropic analysis of modulated signals
摘要：
我们研究的应用程序的量子层析成像框架的调制信号的时频分析。特别是，我们计算光学层析表示和Wigner-Ville分布的振幅和频率调制的信号。我们还考虑调制信号的时频熵关系，这与傅立叶分析是自然相关的。提供了一个基于调制信号的伪Wigner-Ville分布计算光学时频层析图像的数值工具箱。
英文摘要：
We study an application of the quantum tomography framework for the time-frequency analysis of modulated signals. In particular, we calculate optical tomographic representations and Wigner-Ville distributions for signals with amplitude and frequency modulations. We also consider time-frequency entropic relations for modulated signals, which are naturally associated with the Fourier analysis. A numerical toolbox for calculating optical time-frequency tomograms based on pseudo Wigner-Ville distributions for modulated signals is provided.
