Method of residual frequency offset estimation and compensation in multicarrier CDMA system
多载波CDMA系统的残留频率偏移估计及补偿方法*

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.
