Cooperative Spectrum Sensing with Selection Diversity Reception in Cognitive Radio

Abstract

Cognitive radio (CR) is a promising technology where spectrum sensing is the key factor for the recent and future generations. Detection is compromised when a person reports shadowing or fading consequences and that's why performance of spectrum sensing is developed by cooperative spectrum sensing methods. This paper emphasizes on the performance of Cooperative Spectrum Sensing with Selection Diversity Reception in CR. Fusion rule is played at the data fusion center (FC) to take the hard decision by performing the operation of the received signal from different CR users and eventually, the paper shows that the OR rule has better performance than AND as well as MAJORITY rule in Rayleigh fading.
