摘要：
In this paper, frequency offset and phase noise influence and its compensation technique are discussed in the DFT-Spread OFDM system. Simulation results show that DFr-Spread OFDM introduces more interference than OFDM because of DFT spreading phase offset mismatch caused by frequency offset and random phase noise. Data conjugate ICI self-cancellation method is suggested to improve system performance.
