چکیده

There are mainly two frequency-shift methods developed for Q estimation: the centroid-frequency-shift method and the peak-frequency-shift method. Both of the two methods have advantages and disadvantages. Here we discuss and compare the two methods in detail and propose a novel frequency-shift method for Q estimation, which can improve Q estimates by combining the benefits of the two methods together and avoiding their shortcomings.

Q estimation from reflection seismic data for hydrocarbon detection using a modified frequency shift method

As a powerfully diagnostic tool for structural interpretation, reservoir characterization, and hydrocarbon detection, quality factor Q provides useful information in seismic processing and interpretation. Popular methods, like the spectral ratio (SR) method, central frequency shift (CFS) method and peak frequency shift (PFS) method, have their respective limitations in dealing with field seismi...

Estimation of kinematic source parameters and frequency independent shear wave quality factor around Bushehr

In this paper, the shear wave quality factor and source parameters in the near field are estimated by analyzing the acceleration data in Zagros region. Accelerograms recorded by Building and Houses Research Center strong ground motion network have been used. The data have been considered with the magnitude of 4.7 to 6.3 collected from 1999 to 2014. In this approach, the theoretical S-wave displ...

Quality factors estimation using wavelet’s envelope peak instantaneous frequency

We derive an approximate equation combining the quality factor Q, the traveltime of a wave, and the variation of the instantaneous frequency (IF) at the envelope peaks of two successive seismic wavelets, along the wave propagating direction, based on the theory of one-way wave propagation in a 1D viscoelastic medium. We then propose a method (called the WEPIF method) to estimate Q by measuring ...

Carrier Frequency Offset Estimation and I/Q Imbalance Compensation for OFDM Systems

Two types of radio-frequency front-end imperfections, that is, carrier frequency offset and the inphase/quadrature (I/Q) imbalance are considered for orthogonal frequency division multiplexing (OFDM) communication systems. A preamble-assisted carrier frequency estimator is proposed along with an I/Q imbalance compensation scheme. The new frequency estimator reveals the relationship between the ...

A Novel Method for Estimation of The Fundamental Parameters of Distorted Single Phase Signals

This paper proposes a new method for parameter estimation of distorted single phase signals, through an improved demodulation-based phase tracking incorporated with a frequency adaptation mechanism. The simulation results demonstrate the superiority of the proposed method compared to the conventional SOGI (Second-Order Generalized Integrator)-based approach, in spite of the dc-offset and harmon...
