Pilot tone aided measurements to extend the bandwidth of radio frequency applications
(Elsevier B.V., 2016)
A technique to extend the effective measurement bandwidth of a non-coherent vector receiver is presented. This bandwidth extension technique relies on the use of a pilot signal (known a priori), which is added on the signal ...
Harmonics filtering and detection of disturbances using wavelets
(1999-12-01)
Traditional mathematical tools, like Fourier Analysis, have proven to be efficient when analyzing steady-state distortions; however, the growing utilization of electronically controlled loads and the generation of a new ...
Common architecture for discrete wavelet transform analysis and synthesis with sequential and constant processing elements
(2004-10-08)
This paper adresses the problem on processing biological data such as cardiac beats, audio and ultrasonic range, calculating wavelet coefficients in real time, with processor clock running at frequency of present ASIC's ...

Detection of Auditory Cortex Activity by fMRI Using a Dependent Component Analysis
(SPRINGER-VERLAG BERLIN, 2010)
Functional MRI (fMRI) data often have low signal-to-noise-ratio (SNR) and are contaminated by strong interference from other physiological sources. A promising tool for extracting signals, even under low SNR conditions, ...
