Enhanced Detection Algorithms Based on Eigenvalues and Energy in Random Matrix Theory Paradigm
IEEE Access, 2020 This paper considers the problem of spectrum sensing in multi-antenna cognitive radio networks. Energy detection (ED) method for spectrum sensing does not require any information of the source signal and channel, as well as it is suitable for detecting ...

Jordan–Schur Algorithms for Computing the Matrix Exponential
International Journal of Mathematics and Mathematical Sciences, 2023 In this paper, two new versions of the Schur algorithm for computing the matrix exponential of an n×n complex matrix A are presented. Instead of the Schur form, these algorithms use the Jordan–Schur form of A.

On the geometry of border rank algorithms for matrix multiplication and other tensors with symmetry
CoRR, 2016 We establish basic information about border rank algorithms for the matrix multiplication tensor and other tensors with symmetry. We prove that border rank algorithms for tensors with symmetry (such as matrix multiplication and the determinant polynomial) come in families that include representatives with normal forms. These normal forms will be useful

A fast algorithm for matrix balancing [PDF]
, 2013 As long as a square nonnegative matrix A contains sufficient nonzero elements, then the matrix can be balanced, that is we can find a diagonal scaling of A that is doubly stochastic. A number of algorithms have been proposed to achieve the balancing, the

Wireless Sensor Network Localization via Matrix Completion Based on Bregman Divergence
Sensors, 2018 One of the main challenges faced by wireless sensor network (WSN) localization is the positioning accuracy of the WSN node. The existing algorithms are arduous to use for dealing with the pulse noise that is universal and ineluctable in practical ...
