Abstract: this paper presents the formulation of Extended Kalman Filter, Continuous-Discreet case (C-D EKF) and his application to the determination of state of satelite orbit, verifies the performance of the algorithm when it exists a good model for the process and measurement. It is observed the influence of the passage of integration in the estimation and importance that gives to the algorithm to the predictions and measurements.
Specifying And Measuring Aggregate Broadband Noise Of Catv Modulators And Upconverters, Steven I. Rubin, Andre Basovich, Brani Petrovic, Ron D. Katznelson
Specifying And Measuring Aggregate Broadband Noise Of Catv Modulators And Upconverters, Steven I. Rubin, Andre Basovich, Brani Petrovic, Ron D. Katznelson
Ron D. Katznelson
This paper discusses the practical limitations and the subtle assumptions that must be incorporated into the specifications and measurements of Aggregate Broadband Noise of CATV upconverters and digital QAM transmitters. Considerations that govern the accuracy and measurement dynamic range required for such Aggregate Broadband Noise measures are identified. Novel methods involving the separation of the Aggregate Broadband Noise measure into its composites, namely, modulated distortion noise components and other broadband noise components are discussed. Optimal ways in which such measurement techniques have been automated to enable rapid and efficient evaluation of transmitter devices are also presented along with examples of …
Statistical Properties Of Composite Distortions In Hfc Systems And Their Effects On Digital Channels, Ron D. Katznelson
Statistical Properties Of Composite Distortions In Hfc Systems And Their Effects On Digital Channels, Ron D. Katznelson
Ron D. Katznelson
The statistical properties of Composite Triple Beat (CTB) and Composite Second Order (CSO) distortion terms associated with the analog channels carried on Hybrid Fiber Coax (HFC) are presented. Both simulation and measurement results show that such distortion components falling on individual channels have amplitude Probability Density Function that is nearly Rayleigh distributed (having a Standard Deviation of 5.7 dB). It is shown that both CTB and CSO components have peak envelope power fluctuations that exceed their average (measured) power levels by more than 15 dB. The temporal statistical properties of these distortion components demonstrate peak envelope power fluctuations with characteristic …
