the importance of the precision and stability of downlink synchronization in the TD-SCDMA repeater applications is first introduced.Then
on the basis of the simulation results of two different synchronization algorithms for eigenvalue and demodulation achieved with the Advanced Design System(ADS)
their anti-jamming performances are compared.Finally
their advantages and disadvantages and applicability are analyzed and suggestions for improvement presented on the basis of the statistical simulation results and their practical applications in repeaters.
