Choi–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 See more The definition of the cone-shape distribution function is shown as follows: $${\displaystyle C_{x}(t,f)=\int _{-\infty }^{\infty }\int _{-\infty }^{\infty }A_{x}(\eta ,\tau )\Phi (\eta ,\tau )\exp(j2\pi (\eta t-\tau f))\,d\eta \,d\tau ,}$$ See more • Cone-shape distribution function • Wigner distribution function • Ambiguity function • Short-time Fourier transform See more WebJul 31, 2024 · It was first proposed by Hyung-Ill Choi and William J.

WebAug 1, 2024 · Different kernel functions lead to different distributions such as Choi–Williams distribution, pseudo WVD (PWVD)，smooth pseudo WVD (SPWVD), however window function will inevitably reduce TF resolution. It requires trade-off between cross-term removal and TF resolution. WebAbstract. Due to the requirement of signal representation's flexibility for strong noise interference in non-stationary signal processing, the traditional Choi-Williams …
