Abstract
Description
The noncoherent energy detector (ED), an algorithm that detects a primary signal based on the sensed energy, is one of the simplest devices used in cognitive radio (CR) spectrum sensing. Although the sensing performance of the ED has been extensively analysed in the literature, almost all of the
research studies model the noise at the receiver as Gaussian which might not be a valid assumption when the noise exhibits impulsive behavior. Additionally, multipath fading, an inherent phenomenon in wireless propagation, makes the spectrum sensing task more difficult. Motivated by these scenarios, spectrum sensing performance with a single CR deploying the ED is considered in this study under multipath fading and impulsive noise environments.
