Abstract :
Federal Communications Commission (FCC)’s spectrum allocation chart shows that many frequency bands are being allocated to multiple incumbents, overlapping each other. While most frequency bands are licensed, studies suggest utilization rates are between 15% and 85%. Cognitive radio (CR) has been highlighted as a possible candidate in improving spectrum utilization by providing opportunistic spectrum access. A cognitive radio can be defined as a radio that is able to Unlicensed spectrum is becoming increasingly scarce, especially those under 3 GHz. Before a CR can utilize any free frequency, it must first be able to detect these unutilized spectrums. The following section will describe what cognitive radio technology is and also the reason behind why such a technology came into existence. mainly in our project we are trying to implement the spectrum sensing technique in cognitive radio with one of the many types present and that is ENERGY DETECTION TECHNIQUE., which was carried in frequency domain to get the power spectral density
