Abstract: The frequency domain sub-channels pilot frequency synchronization method of DMT system is studied.It is demonstrated that both blocks and samples timing recovery can be realized with this method.The relations between the circular shift interpolation sequence and discrete Fourier transform is found .Such a relation is successfully applied in the DMT system to realize the samples timing recovery.

Key words: pilot synchronization, time synchronization, discrete multiple tone
