Abstract	The SC-FDE (single carrier-frequency domain equalizer) is a field that gathers more and more interest as a modulation scheme for the broadband wireless communications, for simple channel equalization, SC-FDE systems perform equalization in frequency domain instead of time-domain using FFT,IFFT and CP (cyclic prefix) like it user for example in OFDM (orthogonal frequency division multiplexing). In this paper, we propose a new residual timing offset tracking scheme for SC-FDE systems which based on the concept of CP. We analyze the effect of timing offset in a frequency-domain and propose a new method of timing synchronization, Based on the data after decision in SC-FDE receiver, we reconstruct the receive signal. By comparing the received signal and the reconstructed one, a new time offset estimation algorithm is developed. This algorithm has advantages as simple in algorithm, high computation efficiency, high precise in tracking, and requiring no additional pilots. Moreover, we verify the algorithm with a numerical analysis and computer simulation.
