摘　　要：本文主要研究了残留频率偏移（RF0，Residual Frequency Offset）对载波CDMA的系统模型性能的影响。详细分析了残留频率偏移对接收信号产生的影响，同时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，对分块估计多载波CDMA系统在接收端信号的残留频率偏移并进行补偿的方法进行了优化完善。最后给出了仿真结果。The influence of residual frequency offset on the performance of the multi carrier CDMA system model was researched, the effect of the residual frequency offset to the received single was analyzed, with considering the different effects of the Doppler frequency offset to the different subearriers, the method of compensation for the RFO by blocked was to be perfect and optimized . The simulation results were given at the last.
