Abstract: In the invention, a simple and robust method for clock offset compensation is proposed using an equalizer with time-varying signal windowing for which the timing information needed is obtained by an existing non-data-aided (NDA) timing estimator. Instead of interpolating the received signal, the proposed method compensates clock offset by using a moving signal window for equalizer. Since no interpolation is needed, the timing information required for the proposed method need not be so accurate as required for interpolation methods. Rather than the exact time drift due to clock offset, the proposed method requires only the timing points where the time drift accumulates to a pre-defined threshold. By applying an existing non-data-aided (NDA) timing estimator, the needed timing information can be obtained easily. Moreover, thanks to robustness of the NDA timing estimator, the proposed method is inherently robust and simple in implementation.
