Abstract :
Different from multiuser detection, synchronization in multiuser communications systems has its unique features. We revisit effective multiuser synchronizers in a systematic way and classify them into two categories: linear multiuser synchronizers and the multiuser synchronizers based on the frequency domain approach. Both categories of estimators have their special advantages according to their characteristics and are applicable to practical DS/CDMA communications systems
