Enhanced Maximum-Minimum Eigenvalue Based Spectrum Sensing

2019 International Conference on Information and Communication Technology Convergence (ICTC), 2019
The maximum eigenvalue captures the signal correlation well, and the minimum eigenvalue also captures the noise characteristics well, thus the spectrum sensing algorithm based on the maximum and minimum eigenvalue gets better detection performance.

Maximum-Minimum Eigenvalue Detection for Cognitive Radio

2007 IEEE 18th International Symposium on Personal, Indoor and Mobile Radio Communications, 2007
Sensing (signal detection) is a fundamental problem in cognitive radio. In this paper, a new method is proposed based on the eigenvalues of the covariance matrix of the received signal. It is shown that the ratio of the maximum eigenvalue to the minimum eigenvalue can be used to detect the signal existence.

Pole assignment with minimum eigenvalue differential sensitivity

Proceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 1997
This paper introduces a set of mathematical formulae for calculating the eigenvalue differential sensitivities of the closed-loop state matrix with respect to the open-loop state matrix, input matrix and state feedback matrix. It provides a computational procedure for a robust pole assignment problem.
