Polynomial estimation of the amplitude of a signal

IEEE Transactions on Information Theory, 1994
Summary: The problem of estimating the amplitude of a signal is addressed using higher-order statistics. The probability distribution of the noise is assumed to be unknown so that the maximum likelihood estimator cannot be calculated. The estimator is taken as a polynomial of the observation, the coefficients of which are determined so that the ...

Multiple site electromyograph amplitude estimation

IEEE Transactions on Biomedical Engineering, 1995
Temporal 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 ...

A nonlinear approach to estimate the amplitude of a signal

[Proceedings] ICASSP-92: 1992 IEEE International Conference on Acoustics, Speech, and Signal Processing, 1992
The problem of estimating the amplitude of a signal appears in many aspects of signal processing such as, for example, amplitude modulation in communication theory. When the probability distribution of the noise is unknown, the calculation of the maximum likelihood estimator is impossible.

Amplitude estimation with application to system identification

1999 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings. ICASSP99 (Cat. No.99CH36258), 1999
We investigate herein the problem of amplitude estimation of sinusoidal signals from observations corrupted by colored noise. A relatively large number of amplitude estimators are described which encompass least squares (LS) and weighted least squares (WLS) methods.

Estimation of Current Amplitude Pulse

Advanced Materials Research, 2014
Method 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.

Variational estimate of a breakup amplitude

Physical Review C, 1983
Estimates of the correction to the Born amplitude are obtained from a variational principle. A wave packet representation is used to provide an off-shell amplitude in a time-independent theory of collisions. The theory is applied numerically to a breakup reaction p+/sup 3/H..-->..p+n+d.

Estimation of the amplitude of Nonlinear "Anticonvection"

Journal of Engineering Physics and Thermophysics, 2020
In systems consisting of two immiscible liquids in the gravity force field, convective instability may set in not only on heating from below, but also on horizontal-homogeneous heating from above, i.e., on stable density stratification of each of the media.

Unscented Kalman Filter for frequency and amplitude estimation

2011 IEEE Trondheim PowerTech, 2011
This paper introduces a new digital signal processing algorithm for frequency and amplitude estimation based on Unscented Kalman Filter (UKF). The results of computer simulated and realistic synthetic data tests are presented. The initial parameters used during the tests were chosen carefully using an established parameter estimation method, the Self ...

Direction-of-arrival estimation of an amplitude-distorted wavefront

IEEE Transactions on Signal Processing, 2001
In a number of array signal processing applications, such as underwater source localization, the propagation medium is not homogeneous, which causes a distortion of the wavefront received by the array. There has been some interest in the direction-of-arrival (DOA) estimation of such distorted wavefronts.
