1. A method of determining a phase offset between signaling channels in a communication system, comprising the steps of:

  • deriving a first set of channel estimates from symbols received through a first signaling channel;

    deriving a second set of channel estimates from symbols received through a second signaling channel;

    deriving first and second antenna phase estimates from the first and second sets of channel estimates, respectively; and

    determining an estimate of the phase offset based on the set of first and second antenna phase estimates without using the first and second sets of channel estimates.
