Spectrum sensing technology, spectrum sharing technology and spectrum management technology are currently the three core technologies for cognitive radio, amony which spectrum sensing technology is the premise in implementing the following spectrum sharing and spectrum management. This paper focuses on fundamental theory of the current cognitive radio spectrum sensoring technology, algorithm model and specific algorithm, and their classifications. And by using the Matlab simulation platform, simulation on spectrum sensing algorithms is done, and the comparison of simulation results, indicates the performance of each algorithm, thus providing some reference for the users of cognitive radio in their choosing algorithm, and laying a foundation for the subsequent cognitive radio spectrum sharing and spectrum management work.
