Simulink based Cooperative (Hard Decision Fusion) and Non-Cooperative Spectrum Sensing in Cognitive Radio Using Cyclostationary Detection
Niger Fatema | Ikram Ilyas | Dr. Md. Abdur Rahman
Abstract: Radio frequency spectrum is a quite limited resource. With the increased dependence on modern wireless devices, the management and proper utilization of the spectrum has become a major challenge. The concept of cognitive radio aims to overcome these problems by helping to achieve improved spectral management, utilization, and efficiency. To sense the unoccupied spectrum gap is one of the essential tasks of cognitive radio. There are many spectrum sensing algorithms available for cognitive radio. This paper describes cyclostationary based detection method of cooperative and non-cooperative spectrum sensing for cognitive radio. The fusion method used for the cooperative sensing is the hard fusion detection method. Cyclostationary based detection method is used to sense the unoccupied spectrum gap through cyclic autocorrelation function in Simulink. . We also spoke about the basics of Cognitive Radio and implemented Simulink models for both Cooperative and Non-Cooperative spectrum sensing methods. Also the merits and demerits of the Cyclostationary Detection technique has been mentioned. In this research paper all these things have been discussed.
