Patent ID: 7804924

Claim:
A timing recovery comprising: a resampler configured to receive a sampling timing control signal according to timing offsets of current symbols as feedback and control a sampling timing of a complex signal input from a carrier recovery; a DMTED (dispersion minimization timing error detector) configured to receive the sampling timing control signal from the resampler, apply a dispersion constant as a cost function of a CM (constant modulus) algorithm, and estimate timing offset information such that the dispersion constant is reduced by using the CM algorithm, wherein the dispersion constant is obtained by raising the sampling timing control signal to a fourth power and the dispersion constant is estimated by changing a timing offset; a loop filter configured to filter only a low band signal component in the estimated timing offset information output from the DMTED; and a complex oscillator configured to feed the sampling timing control signal back to the resampler for controlling the sampling timing of the resampler by changing an output frequency depending on the low band signal component of the estimated timing offset information.
