Bispectral resolution and leakage effect of the indirect bispectrum estimate for different types of 2D window functions

چکیده
An important practical problem in the area of the higher-order statistical signal processing is to estimate the cumulants and polyspectra of the analyzed signal when a finite sequence of time samples is available. We cannot use the theoretical formula because they are based on the assumption that an infinite sequence of time samples is available, but this is not true in practice. In order to obtain a better estimate for bispectrum of the signal, different types of 2D window functions are used. Also, these windows are investigated in terms of the resolution and leakage effect of the indirect bispectrum estimate. Key-Words: higher-order statistics, bispectrum estimation, 2D window functions, bispectral resolution

The bispectrum and its relationship to phase-amplitude coupling.
Most biological signals are non-Gaussian, reflecting their origins in highly nonlinear physiological systems. A versatile set of techniques for studying non-Gaussian signals relies on the spectral representations of higher moments, known as polyspectra, which describe forms of cross-frequency dependence that do not arise in time-invariant Gaussian signals. The most commonly used of these employ...

متن کاملCompensation of Cross-Contamination in Simultaneous 201Tl/99mTc Myocardial Perfusion SPECT Imaging
Introduction: It is a common protocol to use 201Tl for the rest and 99mTc for the stress cardiac SPECT imaging. Theoretically, both types of imaging may be performed simultaneously using different energy windows for each radionuclide. However, a potential limitation is the cross-contamination of scattered photons from 99mTc and collimator X-rays into the 201Tl energy window. We used a middle en...
متن کاملThe impact of age on bispectral index values and EEG bispectrum during anaesthesia with desflurane and halothane in children.
BACKGROUND The relationship between end-tidal sevoflurane concentration, bispectral index (BIS) and the EEG bispectrum in children appears to be age dependent. The aim of this study was to quantify the BIS values at 1 MAC (minimum alveolar concentration) for desflurane and halothane, and explore the relationship with age for these anaesthetic agents in children. METHODS ECG, EEG and BIS were ...
متن کاملTHEORY AND METHODS OF SIGNSL PROCESSING Signal Reconstruction by Using Normalized Bispectrum Estimates in Noise
The problem of reconstructing an unknown waveform observed in additive noise by using normalized bispectral density estimates is considered. The proposed approach is based on using a continuous-valued normalized bispectral density estimate instead of the discontinuous biphase function conventionally computed in bispectrum-based signal reconstruction algorithms. The performance and reconstructio...
