Total Least Squares Method for Direction of Arrival Estimation [PDF]

open access: yesJisuanji gongcheng, 2019
In the Time Difference of Arrival(TDOA) positioning technology,when the position coordinates of the sensor have errors,the estimated value obtained by the Least Squares(LS) method no longer has the best unbiasedness,resulting in a decrease in the ...

Adaptive State Feedback Control Method Based on Recursive Least Squares

open access: yesElektronika ir Elektrotechnika, 2022
This study revealed an adaptive state feedback control method based on recursive least squares (RLS) that is introduced for a time-varying system to work with high efficiency. Firstly, a system identification block was created that gives the mathematical

A New Endmember Extraction Method Based on Least Squares

open access: yesCanadian Journal of Remote Sensing, 2022
Endmember extraction is frequently adopted to detect spectrally unique signatures of pure ground materials in hyperspectral imagery. These endmembers are the purest pixels in the HSI data cubes. Every pixel in a HSI data cube can be expressed as a linear

A graph interpretation of the least squares ranking method [PDF]

open access: yes, 2014
The paper aims at analyzing the least squares ranking method for generalized tournaments with possible missing and multiple paired comparisons. The bilateral relationships may reflect the outcomes of a sport competition, product comparisons, or ...

An optimal adaptive wavelet method for First Order System Least Squares [PDF]

open access: yes, 2017
In this paper, it is shown that any well-posed 2nd order PDE can be reformulated as a well-posed first order least squares system. This system will be solved by an adaptive wavelet solver in optimal computational complexity.

Reconciling alternate methods for the determination of charge distributions: A probabilistic approach to high-dimensional least-squares approximations [PDF]

open access: yes, 2010
We propose extensions and improvements of the statistical analysis of distributed multipoles (SADM) algorithm put forth by Chipot et al. in [6] for the derivation of distributed atomic multipoles from the quantum-mechanical electrostatic potential.
