Periodogram with varying and data-driven window length
The short-time Fourier transform and the corresponding periodogram give biased estimates of the instantaneous frequency (IF) if the IF in question is a nonlinear function of time. In the case of noisy signals, the optimal choice of the window length, based on asymptotic formulae for the variance and bias, can resolve the bias—variance trade-off usual for nonparametric estimation. However, the p...
متن کاملInstantaneous Frequency Estimation Using The Wigner Distribution With Varying And Data-driven Window - Signal Processing, IEEE Transactions on
Estimation of the instantaneous frequency (IF) of a harmonic complex-valued signal with an additive noise using the Wigner distribution is considered. If the IF is a nonlinear function of time, the bias of the estimate depends on the window length. The optimal choice of the window length, based on the asymptotic formulae for the variance and bias, can be used in order to resolve the bias-varian...
متن کاملAdaptive Segmentation with Optimal Window Length Scheme using Fractal Dimension and Wavelet Transform
In many signal processing applications, such as EEG analysis, the non-stationary signal is often required to be segmented into small epochs. This is accomplished by drawing the boundaries of signal at time instances where its statistical characteristics, such as amplitude and/or frequency, change. In the proposed method, the original signal is initially decomposed into signals with different fr...
متن کاملVarying Characteristics of Bipolar Transistors with Emitter Contact Window Width
On the basis of careful selection and calibration of model parameters we performed process and subsequent device simulation on WEB bipolar transistors. As a result, we concluded, that the mechanical stresses may be responsible for the measured varying device DC characteristics with emitter contact window width.
