Noise reduction by multiplicative waveforms decomposition

Seventh International Symposium on Signal Processing and Its Applications, 2003. Proceedings., 2003
This paper introduces a novel multiplicative noise reduction method based on a particular association of structural and statistical analysis. The structural analysis is performed by a new, multiplicative matching pursuit decomposition (MMPD), that decomposes images containing the intrinsic variation into a nonlinear expansion of waveforms selected from

Adaptive Noise Waveform Design for Radar

2009 IEEE 13th Digital Signal Processing Workshop and 5th IEEE Signal Processing Education Workshop, 2009
This paper introduces an adaptive radar waveform technique where a standard LFM waveform is used as an initial seed. The seed waveform is changed using a phase-only adaptive technique to minimize the resulting waveform's power in specific areas associated with in-band and adjacent-band spectral regions.

Target discrimination technique utilizing noise waveforms

SPIE Proceedings, 2011
Noise waveforms generated using low cost diodes are a simple way for radars to transmit a wideband (> 4 GHz) multi-bit pseudorandom code for use in a cross correlation receiver. This type of waveform also has the advantage of being difficult to intercept and is less prone to interfere with adjacent systems.

Noise waveforms with repetitive phase and nonrepetitive amplitude

Optics Letters, 2002
By use of frequency-shifted feedback lasers, noise with a stationary amplitude and a periodically stationary phase is generated. The ensemble-averaged time correlation function is periodic, whereas the power spectrum is broadband, resulting in a waveform that does not obey the Wiener-Khintchine relations.

Seismocardiography: waveform identification and noise analysis

[1991] Proceedings Computers in Cardiology, 2002
The seismocardiogram (SCG) provides a convenient and reliable measure of left ventricular systolic and diastolic performance both at rest and immediately after exercise. An effective means has been developed to eliminate noise artifacts such as coughing, talking, and patient movement prior to any waveform averaging scheme. A computer algorithm has been
