Collaborative Spectrum Sensing in a Cognitive Radio System with Laplacian Noise

Abstract

The receiver operating characteristic curve is evaluated for a cognitive radio system with Laplacian noise. The characteristic functions and cumulative distribution functions at the output of an energy detector are derived for primary user ON/OFF hypotheses. Approximate closed-form expressions for the probability density functions and cumulative… (More)
