Abstract

Abstract:

A novel recognition algorithm is proposed over frequency selective fading channels to distinguish multi-carrier （OFDM）and single carrier（MFSK、MPSK、MQAM）signals of GLSFBC structure.The proposed algorithm is based on high-order cumulants, only needs to directly process the received IF signals, and doesn't need to know the piror information of transmit signal and channel. Simulation results show that 90% correct classification rate could be reached when SNR is above 7 dB.

Key words: modulation recognition, high-order cumulants, OFDM, GLSFBC
