Choi-William's distribution

The Choi Williams distribution (CWD), is given by the relation,
\begin{displaymath}
\rho(t,f) = \int_{-\infty}^\infty \int_{-\infty}^\infty h\le...
...-\pi^2\sigma\frac{(u-t)^2}{\tau^2} - 2\pi i \tau f} d\tau du,
\end{displaymath} (10.1.223)

where $\sigma$ is the width of the window. As described in section [*] we again need to oversample the data train at least by a factor of two. Also it is to be noted that the Choi-Williams transform is quite expensive to compute.
