摘要：
In LTE-A system, there are generally two types of frequency offset: fixed frequency offset and Doppler frequency offset. In the paper, firstly, the estimation of fixed frequency offset and Doppler frequency offset is introduced, then several improved estimation schemes is proposed. Secondly, with the presence of two types of frequency offset in the system, a joint estimation and compensation algorithm of fixed frequency offset and Doppler frequency offset is proposed. Simulation results show that the proposed algorithms can meet the performance requirements for frequency synchronization of LTE-A system and reduce system block error ratio effectively.
