The radio spectrum is the most source that needs to be utilized using cognitive radio (CR) system Detecting primary users (PU) over the spectrum is one of the problems that face cognitive radio system. To overcome this problem, we use sensing techniques like energy detection, matched filter detection and Cyclostationary feature detection. This paper focuses(More)
