K-Complex Detection Based on Synchrosqueezing Transform
K-complex is an underlying pattern in the sleep EEG. Due to the role of sleep studies inneurophysiologic and cognitive disorders diagnosis, reliable methods for analysis and detection of this patternare of great importance. In our previous work, Synchrosqueezing Transform (SST) was proposed for analysisof this pattern. SST is an EMD-like tool, which benefits from wavelet transform and reallocat...
متن کاملAnalyse de Signaux Multicomposantes : Contributions à la Décomposition Modale Empirique, aux Représentations temps-fréquence et au Synchrosqueezing
Many signals from the physical world can be modeled accurately as a superposition of amplitude-and frequency-modulated waves. This includes audio signals (speech, music), medical data (ECG) aswell as temporal series (temperature or electric consumption). This thesis deals with the analysis of suchsignals, called multicomponent because they contain several modes. The techniques i...
متن کاملOptimal demodulation of PAM signals
Kalman filtering theory is applied to yield an optimal causal demodulator for pulse-amplitude-modulated (PAM) signals in the presence of white Gaussian noise. The discrete-time data (or sampled continuous-time data) are assumed to he either a stationary or nonstationary Gaussian stochastic process, io general nonwhite. Optimal demodulation with delay is also achieved by application of Kalman fi...
متن کاملMulticomponent AM-FM demodulation via periodicity-based algebraic separation and energy-based demodulation
Previously investigated multicomponent AM–FM demodulation techniques either assume that the individual component signals are spectrally isolated from each other or that the components can be isolated by linear time-invariant filtering techniques and, consequently, break down in the case where the components overlap spectrally or when one of the components is stronger than the other. In this pap...
متن کاملDigital Demodulation of Interferometric Signals
The marriage of optical sensing techniques with sophisticated digital signal processing has resulted in a myriad of practical metrology systems. Optical metrology systems offer many attractive measurement features. These systems are inherently non-contacting, nondestructive, and immune from electromagnetic interference. In addition, since light is used as the sensing probe, the measurement syst...
