Spectrum sensing is a primary conception in Cognitive Radio (CR) to improve the spectrum utilization in the current wireless communication with exponential growth in wireless technology. Spectrum allocation governed by the government agencies or the service providers who are in need of spectrum, to manage the increasing frequency demands from the end users as the technology increases exponentially. Current scenario of spectrum sensing needs to improve in terms Signal to Noise Ratio (SNR) values, less complexity and throughput. Even though there are different methods available for spectrum sensing, the need for improved sensing are accomplished by the Cyclostationary sensing method. A Cyclostationary Signal having statistical properties those vary cyclically with time.
