Abstract: This paper aims to research and focus on spectrum sensing in Cognitive Radio which is a recently introduced technology. It helps to increase the spectrum efficiency in cognitive radio. Increasing efficiency of the spectrum usage is a need of an intrinsic result of rapidly increasing wireless users and also the conversion of voice oriented applications to multimedia applications. Static allocation of the frequency spectrum does not needs to current wireless technology where as a dynamic spectrum usage is required for wireless networks. Cognitive radio is considered as a promising candidate to be employed in such systems as they are aware of their operating environments and having ability to adjust their parameters. Cognitive radio can sense the available spectrum and detect the idle frequency bands. The secondary users can be allocates those bands which are not used by primary users. In order to avoid this interference in between primary user by secondary user spectrum sensing is to be needed. There are several spectrum sensing techniques proposed in literature for cognitive radio based systems. This work approaches for energy detection and Cyclostationary feature detection based spectrum sensing systems for cognitive radios in wireless communication channels. Keywords: Cognitive Radio, Feature Detection, Energy Detection, Reconfiguration.
