TIMING RECOVERING SYSTEM

摘要

an A/D converter (200) for converting a received analog signal into digital signal; a timing phase error estimator (210) for estimating the phase error using the output signal of the A/D converter (200) to generate a signal corresponding to the estimated phase error; a hang-up detector (240) for generating a signal indicating the presence of hang-up from the signal corresponding to the estimated phase error; an average calculator (220) for calculating the averag value of the signal generated from the timing phase error estimator (210) to generate a signal corresponding to the averag value; and a controller (230) for generating a control signal to control the sampling time of the A/D converter (200) from the output signal calculated by the average calculator (230).
