Cognitive radio is a novel technology that aims to maximize the utilization of finite spectrum which would otherwise remain idle. One of the important tasks of cognitive radio is to perform spectrum sensing where the secondary unlicensed users search for the idle portions of the licensed spectrum. Cooperative Spectrum Sensing is done by collaboratively detecting the spectrum availability to improve the spectrum sensing performance. In most existing contributions, the reporting channels in a Cognitive Radio (CR) network are considered to be error free which is not the case in practical scenarios. In this paper, a realistic cognitive radio network is considered where both the sensing and reporting channels are considered to be affected by noise uncertainties.
