中文摘要：
结合多载波CDMA的系统模型，考虑了由于多径传输而产生的多普勒频移对接收端不同子载波存在不同频偏的影响；分析了残留频率偏移对接收信号产生的影响，利用在频域内插入导频、分块估计接收端信号的残留频率偏移，并在时域内进行补偿，最后给出了仿真结果。
英文摘要：
The different frequency offset effect to different subcarriers due to the Doppler frequency offset which generated in the multipath propagation was considered, the effect of the residual frequency offset to the received signal was analyzed. Using pilot interpolation in the frequency domain, the amount of RFO could be estimated in blocks of the received signals, and compensated in the time domain. The simulation results were given at the last.
