摘要

L2 (R)中任何函数的时频积都受测不准原理的约束。提出了一种以时频局部化为最优准则的线性相位双正交滤波器组设计方法。设计理念是在确定分析和合成低通滤波器的消失矩数后，通过调整单个参数来优化迭代小波的时频积。

A class of time-frequency product optimized biorthogonal wavelet filter banks

The time-frequency product of any function in L2 (R) is bounded by the uncertainty principle. This paper presents a method to design linear phase biorthogonal filter banks with the time-frequency localization as the optimality criterion. The design philosophy is to optimize the time-frequency product of the iterated wavelet, after fixing the number of vanishing moments of the analysis and synthesis lowpass filters, by adjusting a single parameter.
