With tremendous growth of wireless communication technology, the spectrum utilization is one of the prime challenges. Cognitive radio has been emerged as a key technology which can resolve the issue by sensing, analyzing and allocating the spectrum. There are different spectrum sensing algorithms suggested in the literature. In this thesis, an overview of major sensing techniques is discussed. Although having practical limitations, Energy detection is a popular technique because of its simplicity, low computational complexity and mainly due to no necessity of prior information from primary user. This research is focused on an improved version of energy Detection Technique .The results prove that the improved energy detection based technique gives better performance under lower SNR values.
