The cognitive radio is one of the novel concepts from conventional exclusive spectrum assignment to dynamic spectrum assign. They provide the spectrum for efficient and sufficient utilization of the radio electromagnetic resources. Researches are focuses on the cooperative spectrum sensing technique to increase reliability of the spectrum for cooperative spectrum sensing technique are very difficult to tolerate with both individual node of the wireless network for the short time. In this paper proposes the energy detection method for spectrums sensing on the basis of estimated SNR, it is calculated in advance for available network. The proposed method in which is also analysis performance of the signal to noise ratio (SNR) and the Decision Accuracy using different wavelet family.
