摘要
本文给出判断一类函数是否具有时频局部化的简单方法,并给出计算窗函数半径的公式.基于此判断方法,给出一类具有时频局部化的含参量窗函数.
In this paper, a simple time-frequency localization property radius of the window functions is parameterized window functions with method of judging whether a class of functions is presented, and the formula for calculating given. Based on the judging method, a class time-frequency localization property is obtained.
