Upgrading usages of wireless communication applications have many constraints on the utilization of accessible wireless spectrum. Cognitive radio (CR) technology is an emanate and auspicious solution to the issue of insufficient licensed spectrum. The spectrum sensing is the majority demanding issues in cognitive radio applications to find out the accessible spectrum bands and which can be utilized by secondary user without providing any unfavorable intervention to the primary user. Several conventional spectrum sensing procedures are presented to perceive the primary user signals. This paper reviews the performance of three significant spectrum sensing methods such as Energy detection(ED), matched filtering detection (MFD) and Cyclostationary detection (CD) techniques. All the methods are interpreted based on the parameters of probability of detection (Pd), probability of false alarm (Pf) and signal to noise ratio (SNR) using MATLAB under AWGN channel.
