Discrete time and frequency Wigner-Ville distribution: Moyal's formula and aliasing
Eric Chassande-Mottin, Archana Pai · IEEE Signal Processing Letters · 2005
In this letter, we propose a new definition of the discrete time and frequency Wigner-Ville distribution. The proposed distribution not only displays a readable representation (small aliasing) but also exhibits unitarity and is easy to compute. We compare the time-frequency representation associated with this proposed definition with other existing ones.
