In this paper, we analyze the effect of cooperation for spectrum sensing based on relay with equal gain combining in cognitive radio networks. The performance of energy detection in cognitive radio network over a number of cognitive radio users is evaluated. The probability of detection and probability of false alarm are calculated and simulated. We found that when the square of the sum of the gains...
Traditional wireless networks including wireless sensor networks working in an unlicensed spectrum band are suffered from uncontrolled interference, as this unlicensed spectrum band gets crowded day by day. This problem is not because of spectrum band deficiency, rather it is because of the misuse/inefficient usage of the spectrum bands i.e., fixed spectrum assignment policy. Cognitive Radio (CR)...
