WebMay 1, 1995 · The Choi-Williams distribution The Choi-Williams distribution (CWD) [2,5,9,10,12-14,16,20] is a smoothed WD that re- tains a large number of desirable mathematical prop- erties (see Table 1 ). In particular, the CWD satisfies the marginal properties and is thus an "energy distri- bution". WebJan 1, 1980 · The Wigner-Ville distribution (WVD) [10], the cone-shape distribution (CSD) [11] and the Choi-Williams distribution (CWD) [12] are examples of energy representations. The WVD satisfies a large ...

WebMay 1, 1995 · The smoothed pseudo-Wigner distribution, the Choi-Williams distribution, and the cone-kernel representation are three time-frequency representations (TFRs) which feature an attenuation of cross (interference) terms as compared with the Wigner distribution. In this paper, we use an analysis of ambiguity-domain weighting functions … WebChoi–Williams distribution function is one of the members of Cohen's class distribution function.

It was first proposed by Hyung-Ill Choi and William J. Williams in 1989. This distribution function adopts exponential kernel to suppress the cross-term. However, the kernel gain does not decrease along the axes in the ambiguity domain. raaz name meaning
