Abstract
Spectrum sensing is the Cognitive Radio mechanism that enables spectrum awareness. Spectrum sensing detection performance can be greatly improved, through the use of cooperative sensing schemes.
This paper considers and proposes a cooperative spectrum sensing scheme, which implements an adaptive counting rule to perform the data fusion. The proposed scheme is evaluated against other common counting rules (e.g. 1-out-of-n and n-out-of-n) and the optimum counting rule, under different correlation conditions. The impact of correlation on the performance of the data fusion schemes, based on counting rules has been studied.
The paper finally concludes that the proposed counting rule detection performance reaches the one of the optimum counting rule and adapts to the correlation conditions.
