Frame-theoretic analysis of oversampled filter banks

H Bolcskei, F Hlawatsch… - IEEE Transactions on …, 1998 - ieeexplore.ieee.org
We provide a frame-theoretic analysis of oversampled finite impulse response (FIR) and
infinite impulse response (FIR) uniform filter banks (FBs). Our analysis is based on a new …

Life beyond bases: The advent of frames (Part I)

J Kovacevic, A Chebira - IEEE Signal Processing Magazine, 2007 - ieeexplore.ieee.org
Coming to the end of Part 1, we hope you have a different picture of a frame in your mind
from a" picture frame." While necessarily colored by our personal bias, we intended this …

Acidic properties of sulfated zirconia: an infrared spectroscopic study

F Babou, G Coudurier, JC Vedrine - Journal of Catalysis, 1995 - Elsevier
Sulfated zirconia with S content of 2 wt.% equivalent to complete coverage of its surface was
studied by infrared spectroscopy. At least four sulfated species were identified and exhibited …

An introduction to frames

J Kovačević, A Chebira - Foundations and Trends® in Signal …, 2008 - nowpublishers.com
This survey gives an introduction to redundant signal representations called frames. These
representations have recently emerged as yet another powerful tool in the signal processing …

Life beyond bases: The advent of frames (Part II)

J Kovacevic, A Chebira - IEEE Signal Processing Magazine, 2007 - ieeexplore.ieee.org
While the first part of this article presented most of the basic theoretical developments of
frames, this part is more user friendly. It covers a large number of known frame families …

A first survey of Gabor multipliers

HG Feichtinger, K Nowak - Advances in Gabor analysis, 2003 - Springer
We describe various basic facts about Gabor multipliers and their continuous analogue
which we will call STFT-multipliers. These operators are obtained by going from the signal …

A general formulation of modulated filter banks

PN Heller, T Karp, TQ Nguyen - IEEE Transactions on Signal …, 1999 - ieeexplore.ieee.org
This paper presents a general framework for maximally decimated modulated filter banks.
The theory covers the known classes of cosine modulation and relates them to complex …

Discrete Zak transforms, polyphase transforms, and applications

H Bolcskei, F Hlawatsch - IEEE Transactions on signal …, 1997 - ieeexplore.ieee.org
We consider three different versions of the Zak (1967) transform (ZT) for discrete-time
signals, namely, the discrete-time ZT, the polyphase transform, and a cyclic discrete ZT. In …

[图书][B] Time-frequency analysis and synthesis of linear signal spaces: time-frequency filters, signal detection and estimation, and Range-Doppler estimation

F Hlawatsch - 1998 - books.google.com
Linear signal spaces are of fundamental importance in signal and system theory,
communication theory, and modern signal processing. This book proposes a time-frequency …

Oversampled cosine modulated filter banks with perfect reconstruction

H Bolcskei, F Hlawatsch - … on Circuits and Systems II: Analog …, 1998 - ieeexplore.ieee.org
Oversampled filter banks (FBs) offer more design freedom and better noise immunity than
critically sampled FBs. Due to the increased computational complexity caused by …
