4 What will happen for UP? Three directions: (and others such as mathematical cases) (1)The lower bound or sharper bound; (2)The new forms of UP; (3)The new applications of UP.
5
6 In 2001, Sudarshan Shinde et al. introduced the sharper bound for UP in An uncertainty principle for real signals in the fractional Fourier transform domain, in IEEE TSP: Only for real signals
7 K. K. Sharma and S. D. Joshi, Uncertainty principle for real signals in the linear canonical transform domains, IEEE Trans. Signal Process., vol. 56, no. 7, pp , Only for real signals
8 What about the complex signals?
