Interconnect waveform calculation method with parameter variation
2013 IEEE 10th International Conference on ASIC, 2013This paper presents an interconnect waveform calculation method with parameter variation for high accurate timing analysis. Using circuit moment sensitivity for parameter variation, proposed method successfully calculated the interconnect waveform with less than 50% delay 1.2 (%) error and about 103 order × acceleration compared with PSpice® Monte ...

Methods and bounds for waveform parameter estimation with a misspecified model
2015 49th Asilomar Conference on Signals, Systems and Computers, 2015Parameter estimation for phase modulated signals is an important area of research as it is applicable to many areas ranging from radar signal processing to gravity wave detection. However, in many of these applications, the phase model required to accurately characterize the phenomenology is either unknown or too complex to accurately estimate the ...

Multi-Parameter Pseudo Acoustic Full Waveform Inversion Method in Elastic World
82nd EAGE Annual Conference & Exhibition, 2021Summary In land seismic exploration, low-velocity zone causes the ray path of reflected wave propagating to the detector perpendicularly. Therefore, single-component data is regarded as P-wave data. In this paper, we first derive a new pseudo acoustic wave equation (PAE) in elastic world based on acoustic approximation.

Substructuring Waveform Relaxation Methods with Time-Dependent Relaxation Parameter
2020We present in this paper a modified variant of Dirichlet–Neumann (DNWR) and Neumann–Neumann Waveform Relaxation (NNWR) methods for solving time-dependent Partial Differential Equations (PDEs). These two domain decomposition methods are based on non-overlapping splitting of domains.

Waveform-based source location method using a source parameter isolation strategy
GEOPHYSICS, 2017We have developed a novel acoustic-wave-equation-based full-waveform source location method to locate microseismic events. With the acoustic-wave equation and source signature independent inversion strategy, source location parameters (hypocenter locations) can be isolated from others and can then be retrieved independently and accurately, even when ...

ICASSP 2023 - 2023 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2023
Among the approaches used to jointly estimate the directions of arrival (DOAs) of K targets in a multiple-input multiple-output dual-function radar communication system, the method based on the identification of the K largest local maxima of the modulus of the Fourier transform (FT) of the signal received by the antennas has the advantage of having a ...

Novel broadband asymptotic waveform evaluation method and its applications in parameter extraction
International Journal of RF and Microwave Computer-Aided Engineering, 2007A new technique to estimate the effective bandwidth of the asymptotic waveform evaluation (AWE) method is proposed, which guarantees the reliable application of AWE in a certain region. Furthermore, based on the effective bandwidth estimation, we develop a novel broadband AWE method, which is an extension and improvement of the conventional AWE method.

Robust Method For Estimating The Parameters Of A Linear Fm Waveform
[Proceedings] IGARSS '92 International Geoscience and Remote Sensing Symposium, 2005In this paper the problem of estimating the linear and quadratic components of a chirp signal is addressed. Areas of application include adaptive optics, coherent imaging, and interferometry. These applications share the common problem of estimating the phase parameters of a received waveform.
