cognitive radio is the solution for effectively utilizing the underutilized radio spectrum. There are many techniques to sense spectrum using cognitive radios like matched filter detection, energy detection, waveform based detection, cyclostationary feature detection and so on. In this paper comparative analysis of two popular techniques i.e. energy detection (ED) and cyclostationary feature detection (CFD) is discussed. Analysis is carried out by discussing the theoretical aspect of both the techniques supported by simulation graphs and plots. This analysis shows that among the two techniques discussed CFD shows better results
