Cognitive radio is a wireless communication where a transceiver can detect the utilization of channel in a network. The major element used in cognitive radio is spectrum sensing, which mainly focus on improvement of spectrum utilization by enabling opportunistic access users through heterogeneous architectures and dynamic process. Spectrum sensing is more complex because signal detection and modulation classification are two main tasks can automatically identify modulation scheme. But the analysis of modulation scheme to demodulate the receiver signal is comprised once user uses cyclostationary algorithm.
