Abstract :
A spectrum holes sensing approach is developed for Cognitive Radio (CR) systems based on the estimation of the Stokes parameters of partially polarized electromagnetic waves. The performance of the proposed approach is compared with the energy detection method. An expression for the probability of detection based on the proposed method is derived using α - μ generalized gamma fading model.
