In recent days, most of the users relay on wireless applications to do their works. Most of the wireless works carried out through mobile applications. Huge spectrum is necessary for all wireless applications. Since spectrum is precious and less availability, there is a necessity to detect under-utilized spectrum. Cognitive radio take the responsibility to identify the unused spectrum and allot it on opportunistic manner. In this paper, various spectrum detection techniques are discussed. In this paper, discussed merits and demerits of techniques. Challenges in spectrum management is also discussed.
