Abstract In this paper, An analysis method of effects of frequency offset on the property of pulse shaping multicarrier system is presented. The method first divides demodulator output into signals and interference, and then based on the cross-ambiguity function of transmit pulse and receive pulse, obtaines the quantitative analysis of signal and interference, finally calculates the SIR with the utilization of statistical properties of the transmit data. Simulation results show that BER caused by frequency synchronization error is consistent with theoretical calculation of the SIR. Therefore, the reliability of the method is verified.
