1. An apparatus, comprising:

  • a processor operative to perform quick frequency tracking to obtain at least one frequency error estimate for at least one finger processor and to perform quick time tracking to obtain at least one timing error estimate for the at least one finger processor; and

    a demodulator operative to perform detection for signaling with the at least one frequency error estimate and the at least one timing error estimate for the at least one finger processor;

    wherein the quick frequency tracking comprises an open-loop frequency estimation technique; and

    wherein the demodulator is operative to filter pilot symbols with a non-causal filter to obtain pilot estimates and to perform detection for the signaling based on the pilot estimates.
