Abstract
A carrier recovery process for a received signal comprises estimating the signal carrier frequency, and estimating the signal phase after frequency estimating. During frequency estimating, signal equalizing is performed, during which an equalizer comprising a direct adaptive filter and a recursive adaptive filter adapts only the coefficients of the recursive adaptive filter. During phase estimating, the equalizer adapts only the coefficients of the recursive adaptive filter for a predetermined time.
