Amplitude-only versus amplitude-phase estimation
IEEE Transactions on Instrumentation and Measurement, 1990The feasibility of transfer function estimation based on amplitude-only measurements is investigated, and this method is compared with the amplitude-phase (full complex spectrum) method. It is shown that the amplitude-only-based method is a feasible alternative to the full complex spectrum method when the minimum in-phase transfer function of the ...

Single site electromyograph amplitude estimation
IEEE Transactions on Biomedical Engineering, 1994Previous investigators have experimentally demonstrated and/or analytically predicted that temporal whitening of the surface electromyograph (EMG) waveform prior to demodulation improves the EMG amplitude estimate [1]-[6]. However, no systematic study of the influence of various whitening filters upon amplitude estimate performance has been reported ...

Multiple site electromyograph amplitude estimation
IEEE Transactions on Biomedical Engineering, 1995Temporal whitening of individual surface electromyograph (EMG) waveforms and spatial combination of multiple recording sites have separately been demonstrated to improve the performance of EMG amplitude estimation. This investigation combined these two techniques by first whitening, then combining the data from multiple EMG recording sites to form an ...

Amplitude-division parallel LMS estimator
2008 51st Midwest Symposium on Circuits and Systems, 2008This paper presents a novel tracking technique for rapidly time-varying channels. The proposed scheme supposes multiple linear transversal filters (estimators), which are constructed in a parallel structure. The coefficient vectors for each estimator are adapted by the least mean square (LMS) algorithm according to the information of the channel ...

Estimation of Current Amplitude Pulse
Advanced Materials Research, 2014Method of estimation of current amplitude (~10 kA) pulses constructed by powerful current pulse generator is suggested. It bases on the solution of differential equation current and voltage change on capacitor. The final formula consists of maximum value of capacitor charge, maximum negative voltage value, pulse duration and capacitor value.

Vortex Fiber Mode Amplitude Estimation
Conference on Lasers and Electro-Optics 2012, 2012Fibers that support stable propagation of orbital angular momentum states require novel methods of characterization. We present a method for coherently estimating the mode amplitudes present in such fibers, from near-field intensity measurements.

Reduced-Complexity Nonlinear Soliton Amplitude Estimators
IEEE Photonics Technology Letters, 2019Recent work by Zhang and Kschischang demonstrates how soliton amplitude estimation can be improved by using a nonlinear Fourier transform to separate the solitonic and non-solitonic components of a noisy soliton allowing for the exploitation of correlated noise.

Robust estimation of signal amplitude
IEEE Transactions on Information Theory, 1972An iterative estimation procedure involving the use of a light limiter is proposed for obtaining robust estimates of the amplitude of a signal of known form in additive nearly Gaussian noise. In the case of a constant signal the procedure, referred to as the iterative limiter estimator (ILE), is exhibited as a form of stochastic approximation and the ...

On estimating random amplitude chirp signals
1999 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings. ICASSP99 (Cat. No.99CH36258), 1999This paper considers the problem of estimating the parameters of chirp signals with randomly time-varying amplitude. Two methods for solving this problem are presented. First, a nonlinear least-squares approach (NLS) is proposed. It is shown that by minimizing the NLS criterion with respect to all samples of the time-varying amplitude, the problem ...

Estimation of resonant peak amplitudes
Journal of Sound and Vibration, 1975A simple method is proposed for estimating the resonant peak response levels of damped structures, by using an analysis of undamped vibration. The method is based on a simple identity which is exact for a single degree of freedom system and approximate for more general systems.
