Abstract :
The Wigner distribution (WD) has recently received much attention from researchers interested in dual time/frequency or space/spatial-frequency signal representation. However, an adequate computable approximation to the WD has been lacking. In order to fill this void, we introduce in this paper a new and highly versatile approximation known as the composite pseudo Wigner distribution (CPWD).
