This paper deals with modulation classification under the alpha-stable noise condition.Our goal is to discriminate orthogonal frequency division multiplexing(OFDM)modulation type from single carrier linear digital(SCLD)modulations in this scenario.Based on the new results concerning the generalized cyclostationarity of these sig-nals in alpha-stable noise which are presented in this pa-per,we construct new modulation classification features without any priori information of carrier frequency and timing offset of the received signals,and use support vec-tor machine(SVM)as classifier to discriminate OFDM from SCLD.Simulation results show that the recognition accuracy of the proposed algorithm can be up to 95%when the mix signal to noise ratio(MSNR)up to-1dB.
