摘要：

OQAM/OFDM is a sort of multicarrier signal based on the orthogonal filter bank, and its special generation procedure determines the complexity of cyclic spectral structure. According to the continuous-time baseband model of OQAM/OFDM system, the second-order cyclostationarity of OQAM signals is proved, and the explicit expression of spectral correlation function is derived, meanwhile, the features of Spectral Correlation Function (SCF) for OQAM and the influence of multipath fading channel are investigated. Simulation results sustain the theoretical analysis.
