Abstract
Cognitive radio networks (CRN) are smart networks that automatically sense the channel and adjust the network parameters accordingly. Cognitive radio is emerging technologies that enable the dynamic deployments of highly adaptive radios that are built upon Software Defined Radio (SDR) technology. The radio technology allows the unlicensed operation to be in the licensed band. The cognitive radio network paradigm raises many technical challenges such as the power efficiency, spectrum management, and environmental awareness. The aim of this paper is study, analyze, adaptive cognitive radio network using MATLAB software. The parameters which were taken into consideration of the adaptation were the type of digital modulation, signal to noise ratio and AWGN. The result was obtained in graphical for Bit Error Rate versus signal noise ratio and a modulation signal for primary signal and secondary signal users.
