Covariance Blind Detection Method Based on Eigenvector in Cognitive Radio Network

open access: yesDianxin kexue, 2015
As the blind detection algorithm has the shortcoming that they need information about the channel and more than two cognitive users to detect the primary user,a new blind detection algorithm based on eigenvector using the difference of correlation ...

Robust algorithm for gain-and-phase errors estimation against the direction deviations of calibration sources

open access: yesTongxin xuebao, 2012
The direction deviations of the calibration sources would significantly degrade the calibration accuracy of array gain-and-phase errors.Aiming to this problem,a robust calibration algorithm for gain-and-phase errors against the location deviations was ...

The characteristic polynomial of some anti-tridiagonal 2-Hankel matrices of even order

open access: yesKuwait Journal of Science, 2019
In this paper we derive the characteristic polynomial for a family of anti-tridiagonal 2-Hankel matrices of even order at the expense of Chebyshev polynomials giving also a representation of its eigenvectors.
