摘要：The main motive to design this implementation to analysis Cognitive Radio technology (CR) is
spectrum sensing. The characteristic of this spectrum sensing the electromagnetic atmosphere to settle in their
operation for better radio operating parameters. One of the challenges for CR is to detect the primary users present over
the spectrum. That presents the Maximum Eigen value Based energy detection and .Also highlighted the effect of
different parameters like number of samples, signal to noise ratio in addition apply comparison between the two
methods using the simulation technique. In this paper describe spectrums sensing technique but the main work is
carried for energy detection methods. Energy detection technique is implemented using MATLAB simulation and the
obtained results are plotted using MATLAB simulation The performance of these two methods is evaluated in terms of
their Receiver Operating Characteristics (ROC curves) and their detection probability for different values of Signal to
Noise Ratio (SNR) and of smoothing factor L. OR rule and rule majority rule also discussed.
