1. A method for accurate synchronization using symbol decision feedback on a symbol by symbol basis by determining an optimal sampling phase using a current symbol decision in a circuit having a plurality of correlators, comprising the steps of:

  • selecting the correlator output corresponding to the current symbol decision during the current symbol period generated by a current synchronization clock providing the selected correlator output;

    estimating the optimal sampling phase of the current symbol period from the selected correlator output to provide an adjustment signal;

    adjusting a subsequent symbol'"'"'s synchronization clock pulse based upon the adjustment signal.
