A Frequency Estimation for TD-SCDMA UE
It describes a method to implement frequency offset estimation (FOE) in cell search of the TD-SCDMA system.The received SYNC-DL data is used to calculate frequency offset (FO) before the scrambling code and the Midamble ID is identified.The received Midamble data can be used to calculate FO before Multi-frame synchronization.The FOE with two stages can be used in the same 64chip calculation structure and the hardware resources can be conserved.The simulation results show that the method can control the residual FO within 0.05PPM by smoothing of sub-frame or ⅡR filtering,which meets the TD-SCDMA system requirements for residual frequency,even though a certain sample bias exist.
