摘要

基于小波变换的信号处理是一种新的信号逼近工具。它在信号压缩、自适应、分类和增强等方面有广泛的应用。传统小波系统的总延迟是固定的，因为它取决于线性相位半带滤波器的对称点。在本文中，我们介绍了一种新的滤波器组和小波系统的原理和设计，其中总延迟可以是任意奇数。得到的小波是双正交的。这种新的小波在延迟时间很重要的应用中是至关重要的。

Variable-delay dyadic wavelets

Signal processing based on the wavelet transform is a new tool for signal approximation. It finds applications in signal compression, adaptation, classification and enhancement. The overall delay in a conventional wavelet system is fixed since it depends on the symmetry point of a linear-phase halfband filter. In this paper, we introduce the theory and design of a new filter bank and wavelet system where the overall delay can be any odd integer. The resulting wavelet is biorthogonal. This new wavelet is crucial in applications where the delay time is important.
