WebOct 10, 2024 · Higher order spectrums also proposed a superior analysis than other methods like short time Fourier transform (STFT) and wavelets. Bispectrum algorithm suppresses all phase relation in the signals; therefore, it is mainly used in detecting and quantifying the phase coupling in the non-gaussian signals as well. WebJun 1, 2014 · Abstract This paper describes an invariants generation method for color images, which could be a useful tool in color object recognition tasks. First, by using the algebra of quaternions, we...

WebJul 9, 2024 · Graphene on different substrates, such as SiO2, h-BN and Al2O3, has been subjected to oscillatory electric fields to analyse the response of the carriers in order to explore the generation of terahertz radiation by means of high-order harmonic extraction. The properties of the ensemble Monte Carlo simulator employed for such study have … WebApr 14, 2006 · Finally, some application areas of higher order spectral analysis like removal of Gaussian noise, identification of non-minimum phase systems, and detecting … WebAbstract. Until the mid-1980’s, signal processing — signal analysis, system identification, signal estimation problems, etc. — was primarily based on second-order statistical information. Autocorrelations and cross-correlations are examples of second-order statistics (SOS). The power spectrum which is widely used and contains useful ... jobs that are going to be in high demand
