A detailed algorithm design for initial cell search in LTE system is proposed,which includes timing synchronization,frequency offset estimation,blind detection type of cycle prefix,cell ID and cell ID group identifying and frame synchronization.And among these,the timing synchronization,frequency offset estimation and cell ID identifying are accomplished by primary synchronization signal in time-domain,while blind detection type of cycle prefix,the cell ID group identifying and frame synchronization achieved by secondary synchronization signal in frequency-domain.Both the theory analysis and simulation results show that the algorithm proposed has good performance both in AWAG and multipath fading channels,and can satisfy the performance demand by cell search in LTE system.
