Positivity and spread of bilinear time-frequency distributions (English)
0 references
In this chapter we consider time-frequency distributions that, just like the Wigner distribution, involve the signal bilinearly and that have correct shift properties in the sense that shifts of the signal in time and/or frequency are reflected by corresponding shifts of the distributions in the time and/or frequency variable. This class is often called Cohen's class. A detailed description is given in paragraph 1.2 which will not be repeated here.NEWLINENEWLINEFor the entire collection see [Zbl 0931.00024].
