In this paper, the distribution of the ratio of extreme eigenvalues of a complex Wishart matrix
is studied in order to calculate the exact decision threshold as a function of the desired …

This paper investigates the distribution of the condition number of complex Wishart matrices.
Two closely related measures are considered: the standard condition number (SCN) and the …

Herein, we present a detailed analysis of an eigenvalue-based sensing technique in the
presence of correlated noise in the context of a cognitive radio (CR). We use standard …

Spectrum sensing for cognitive radio allows a secondary user to detect spectrum 'holes' and
to opportunistically exploit this space for unlicensed communication. Blind spectrum sensing …

In this article, a novel spectrum sensing technique for cognitive radio (CR) is proposed
where eigenvalues of the covariance matrix of the received signal are used as features for …

In multi-antenna broadcast networks, the base stations (BSs) rely on the channel state
information (CSI) of the users to perform user scheduling and downlink transmission …

Cognitive radio is an emerging wireless technology that is capable of efficiently coordinating
the use of the currently scarce spectrum resources, and spectrum sensing constitutes its …

In this paper, the distribution of the test-statistic for the covariance based detection (CBD) is
studied in order to obtain the mathematical expressions of false alarm probability (Pf) and …

A novel spectrum sensing algorithm based on support vector machine is proposed. The idea
is to map the received signals into a multi-dimensional feature space obtained from well …

Eigenvalue-based spectrum sensing (EBSS) techniques may operate in a totally blind
manner while they offer remarkably improved performance for specific types of signals …
