A flexible tiling of the time axis for adaptive wavelet packet decompositions
نویسندگان
چکیده
A segmentation procedure of time sequences based on a time-frequency analysis is presented in this paper. The use of both a wavelet packet transform and the original time signal provides a set of spectral and time parameters that allows the algorithm to locate some proper break points to split the input frame into a discrete number of smaller segments. Some examples showing the performance of the method are also presented. An application to wavelet-based audio coding is brie y discussed.

Updating Optimal Coefficients and Selected Observations Affine Projection is an effective way to reduce the computational and power consumption of this algorithm in the application of adaptive filters. On the other hand, the calculation of this algorithm can be reduced by using subbands and applying the concept of filtering the Set-Membership in each subband. Considering these concepts, the fir...

This correspondence investigates M -band wavelet packets and a generalized framework for the design and efficient utilization of multirate filter bank trees (FBTs). While the increased flexibility of M -band wavelet packets over the standard 2-band wavelet packets is desirable in many signal processing applications, the possibilities in time-frequency design using arbitrary filter bank cascades...

Extended Abstract Wavelet packets 14] represent a generalization of the method of multires-olution decomposition and comprise the entire family of subband coded (tree) decompositions 11, 15]. Whereas in the wavelet case the decomposition is applied recursively to the coarse scale approximations (leading to the well known (pyramidal) wavelet decomposition tree), in the wavelet packet decompositi...
متن کاملA New Orthonormal Wavelet Packet Decomposition for Audio Coding Using Frequency-varying Modulated Lapped Transforms
Wavelet packet decompositions based on tree structured 2-channel filter banks with conjugate quadrature filters (CQF) have recently found many applications in the area of audio coding. Their time-frequency tiling is dual to that of timevarying modulated lapped transforms (MLT). In this paper we present a new orthonormal wavelet packet basis, which is constructed by frequency-varying MLT. These ...
متن کاملSpread spectrum interference suppression using adaptive time-frequency tilings
Interference suppression in spread spectrum communication systems is often essential for achieving maximum system performance. Existing interference suppression methods do not perform well for most types of nonstationary interference. We rst consider interference suppression schemes based on adaptive orthogonal time-frequency decompositions, such as wavelet packet and arbitrary dyadic time-freq...
