Optoelectronic broadband signal processor

OSA Annual Meeting, 1993
Because of its low loss (<0.2 dB/km) and low dispersion (<17ps/nm/km), optical fiber has been widely recognized for its potential in delay line signal processing applications [3, 4, 5]. However, the high insertion loss of optical switches and the high cost of optical amplifiers restrict the implementation of a reconfigurable optical fiber delay ...

Detecting nonlinear oscillations in broadband signals

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2009
A framework for detecting nonlinear oscillatory activity in broadband time series is presented. First, a narrow-band oscillatory mode is extracted from a broadband background. Second, it is tested whether the extracted mode is significantly different from linearly filtered noise, modeled as a linear stochastic process possibly passed through a static ...

Detection of broadband dispersive signals

IEEE International Conference on Systems Engineering, 1989
Several methods are developed for detection of signals with known frequency characteristics, such as detection of chirp radar signals using matched filters. An innovative method of detecting broadband dispersive signals is proposed where the known characteristics of exponential frequency decay form the basis of detection.

Section processing of broadband signal

2010 The 2nd Conference on Environmental Science and Information Application Technology, 2010
The purpose of this paper is to segment wide signal. The methods and advantages of the method employed (1) In band-pass filter, used multi-rate during the signal sampling to reduce computation and storage. (2) Used Filter Banks process wide frequency signal, to overcome the drawbacks and deficiencies that large volume calculation bring about when using
