Block-wise recursive sliding variational mode decomposition method and its application on online separating of bridge vehicle-induced strain monitoring signals

D Dan, G Zeng, R Pan, P Yin - Mechanical Systems and Signal Processing, 2023 - Elsevier
A critical element of structural intelligence monitoring is to separate the vehicle-induced
response from the original monitoring signal in real time. To separate the vehicle-induced …

Classification of nonexpansive symmetric extension transforms for multirate filter banks

CM Brislawn - Applied and computational harmonic analysis, 1996 - Elsevier
This paper describes and classifies a family of invertible discrete-time signal transforms,
referred to assymmetric extension transforms (SET's), for finite-length signals. SET's are …

An efficient forecasting approach to reduce boundary effects in real-time time-frequency analysis

A Meynard, HT Wu - IEEE Transactions on Signal Processing, 2021 - ieeexplore.ieee.org
Time-frequency (TF) representations of time series are intrinsically subject to the boundary
effects. As a result, the structures of signals that are highlighted by the representations are …

Theory of cyclic filter banks

PP Vaidyanathan, A Kirac - 1997 IEEE International …, 1997 - ieeexplore.ieee.org
We introduce the fundamentals of cyclic multirate systems and filter banks and present a
