Spectrum sensing technology, spectrum sharing technology and spectrum management technology are the three core technologies of current cognitive radio. Spectrum sensing technology is the precondition for subsequent spectrum sharing and spectrum management. Therefore, the current cognitive radio spectrum sensing technology, the basic theory of the algorithm model and the detailed spectrum sensing algorithm detailed classification, and the use of Matlab simulation platform for the main spectrum sensing algorithm is simulated, and based on the simulation results, compared The advantages and disadvantages of each algorithm can provide a reference for the selection of algorithms for cognitive radio users and lay a foundation for subsequent spectrum sharing and spectrum management of cognitive radio.
