As, the radio spectrum for transmission is very limited but the usage of spectrum is increasing. So, to solve spectrum problem, new method is used. Wher ethe vacant spectrum sense by detector. There are different methods are used for spectrum sensing which are Transmitter detection, Co-operative detection, Interference base detection. In this paper transmission type coherent detection technique is used for spectrum sensing. For sensing the spectrum ROC curve is used where absent or present of primary users is sense through the probability of detection.
