摘要：
The invention is related to a synchronization method in a communication system. The invention includes: carrying out a coarse time offset and frequency offset estimation, first estimating errors in the coarse time-offset and frequency offset estimation by using a maximum-likelihood time-offset estimation and joint optimisation of time-offset and frequency-offset, second estimating frequency offset and time offset by using error estimates in a closed tracking loop.
