The resource of radio frequency spectrum is not efficiently managed, and the increased dependence on wireless devices in the modern era just adds to the problem. The concept of cognitive radio aims to overcome the problem of limited radio frequency spectrum by helping to achieve improved spectral management, utilization, and efficiency. One of the ways to improve the efficiency and utilization of an available frequency spectrum is to share it between the users. One of the most important step for spectrum sharing is spectrum sensing. There are many spectrum sensing algorithms available for cognitive radio. This paper describes the Cyclostationary Detection based method of non-cooperative and cooperative cognitive spectrum sensing. The basics of Cognitive Radio have been discussed, and Simulink models have been developed for the detection techniques. Based on the output results of the simulations, the performance of the Non-cooperative Method and the SLC Method of Cyclostationary Spectrum Sensing was compared, and discussed which of the methods have better performance and efficiency.
