For signal analysis in the management and monitoring of the radio spectrum, it is need to automatically identify the modulated signal. This paper performs clustering algorithm on signal constellation diagram after equalization through AP clustering method, and proposes a clustering method for limited problem of modulation recognition type. After normalizing the shape of the constellation diagram, the size of the constellation diagram, and signal AP clustering, it realizes the matching recognition of the constellation diagram. The simulation results show that the AP clustering has efficient recognition ability.
