In the present day Cognitive Radio has become a realistic option for solution of the spectrum scarcity problem in wireless communication. One of the most challenging issues in cognitive radio systems is spectrum sensing concepts, which is considered an extremely well researched topic. In this paper we compare three main classes of spectrum sensing techniques (Energy detection, matched filtering and cyclostationary) analysis in terms of time and spectrum resource consumed required prior knowledge and complexity. We then rank the three classes according to accuracy and performance.
