sensing in cognitive radio networks under multiple primary users condition using multi-class support vector machine (SVM) algorithms. First, we formulated the spectrum sensing problem under multiple primary users scenario as a multiple class signal detection problem where each class is comprised of one or more sub-classes and generalized expressions for the possible classes are provided. Next, we...
The successful implementation of dynamic spectrum access in cognitive radio networks requires that the secondary user has an autonomous knowledge of the true status of the licensed user activities. This paper investigates and proposes a robust blind spectrum sensing technique that is based on the variational Bayesian learning for Gaussian mixture model framework for use in multi-antenna cognitive...
Cognitive radio has been described as the panacea to the problem of ever growing demand and scarcity of the radio spectrum. Fundamental to the successful implementation of cognitive radio is spectrum sensing. Here, we propose and investigate the performance of eigenvalue and support vector machine (SVM) based learning approach for spectrum sensing in multi-antenna cognitive radios. The simulation...
