An Algorithm for Estimating the Signal Frequency at the Output of a Channel with a Controlled Information Flow under Phase Noise Conditions

open access: yesМоделирование и анализ информационных систем, 2021
Research in the field of efficient frequency estimation algorithms is of great interest. The reason for this is the redistribution of the role of additive and phase noise in many modern radio-engineering applications.

Porfolio size, non-trading frequency and portfolio return autocorrelation [PDF]

open access: yes, 2014
In this paper we re-examine the relationship between non-trading frequency and portfolio return autocorrelation. We show that in portfolios where security specific effects have not been completely diversified, portfolio autocorrelation will not increase ...

Tide level in time and frequency domains at Dili port: Characteristic feature of a Lorentz oscillator

open access: yesPhysics of Complex Systems, 2021
Tide level during one year in time-domain measured at Dili port (East Timor) is analyzed by the frequency spectrum with the Fast Fourier Transform (FFT), together with the autocorrelation function (AF).
