Symbol timing recovery circuit
Abstract:
Disclosed is a symbol timing recovery circuit which includes an interpolator to generate, using a first filter, interpolation data of an input signal; a forward equalizer to eliminate, using a second filter, a forward interference wave from the input signal based on the interpolation data, and to output the resultant signal after the elimination, a first identification signal, and a first error signal; a backward equalizer to eliminate, using a third filter, a backward interference wave from the input signal based on the interpolation data, and to output the resultant signal after the elimination, a second identification signal, and a second error signal; and a timing recovery unit to generate a tap coefficient of the first filter, based on a tap coefficient of the second filter, a tap coefficient of the third filter, the first identification signal, the first error signal, the second identification signal, and the second error signal.
