    摘要： A timing recovery for recovering a symbol clock using received data is provided. The timing recovery estimates a timing offset in such a way that dispersion constants of received symbols are minimized. Since the dispersion constants do not totally depend on a specific portion of a received signal spectrum, deterioration of the timing recovery performance by fading of a specific frequency component can be prevented. Particularly, the timing offset can be stably captured in a frequency selective fading channel such as a multi-path channel.
