Spectral Analysis of Incoherent Scatter Radar Signals in Faraday/Double Pulse Experiments at the Jicamarca Radio Observatory
(IEEE, Institute of Electrical and Electronics Engineers, 2021)
The Jicamarca incoherent scatter radar can be operated in different modes to measure the main physical parameters of the equatorial ionosphere. One of these modes is the Faraday/Double Pulse experiment that was designed ...
Modeling and measuring double-frequency jitter in one-way master-slave networks
(ELSEVIER SCIENCE BV, 2009)
The double-frequency jitter is one of the main problems in clock distribution networks. In previous works, sonic analytical and numerical aspects of this phenomenon were studied and results were obtained for one-way ...
Spectral properties of chaotic signals generated by the skew tent map
(ELSEVIER SCIENCE BV, 2010)
Chaotic signals have been considered potentially attractive in many signal processing applications ranging from wideband communication systems to cryptography and watermarking. Besides, some devices as nonlinear adaptive ...
Spectral properties of chaotic signals with applications in communications
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
This paper investigates the characteristics of the Power Spectral Density (PSD) of chaotic signals generated by skew tent maps. The influence of the Lyapunov exponent on the autocorrelation sequence and on the PSD is ...
Acoustic Imaging of In-Duct Aeroengine Noise Sources Using Rotating Beamforming and Phased Arrays
(Ieee-inst Electrical Electronics Engineers Inc, 2017-09-01)
An in-duct rotating beamforming technique, using a wall-mounted array of microphones placed within a long duct, was developed for locating broadband noise sources from an aeroengine fan. The technique was experimentally ...
Time response measurements of pressure sensors using pink noise technique
(Sao Paulo: ABEN, 2009, 2014)
Postural control during kneeling
(SPRINGER, 2008)
Postural control was studied when the subject was kneeling with erect trunk in a quiet posture and compared to that obtained during quiet standing. The analysis was based on the center of pressure motion in the sagittal ...
Mechanism of interchange between the reflections in a channel of communications with the power spectral density
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ingeniería, 2017-05-01)
The theoretical limit given by the Shannon Capacity equation has been the origin of communications systems based on the interchange between bandwidth and power. This article explores the interchange between the power ...
