About: Choi–Williams distribution function

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

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 axes in the ambiguity domain. Consequently, the kernel function of Choi–Williams distribution function can only filter out the cross-terms that result from the components that differ in both time and frequency center.

  • 崔-威廉斯分布（英語：Choi-Williams distribution function）是科恩克萊斯分佈系列函數中的一種。崔-威廉斯分布於西元1989年由 Hyung-Ill Choi 和 William J. Williams 提出。本分布使用了指數核心函數以濾除交叉項。崔-威廉斯分布之核心函數不隨 和 增加而增加，故只能濾除具有不同頻率和時間中心之交叉項。 (zh)
