Abstract:
1. A method for synchronizing common broadcasts from multiple transmitters, the method comprising: establishing a first delay value for a first terrestrial broadcast signal transmitted from a first terrestrial transmitter based upon a propagation delay of a satellite broadcast signal on a shared frequency between the first terrestrial transmitter and a broadcast satellite; measuring a signal quality factor to identify a region within a coverage area of the first terrestrial transmitter where a combination of signals from the first terrestrial transmitter and the broadcast satellite is most advantageous; and adjusting the first delay value of the first terrestrial broadcast signal based on the measured signal quality factor within the identified region of the coverage area, wherein delaying transmissions of the terrestrial broadcast signal from the first terrestrial transmitter by the first delay value allows a wireless communication device receiving the first terrestrial broadcast signal and the satellite broadcast signal to combine the first terrestrial broadcast signal and the satellite broadcast signal to obtain an enhanced shared frequency received signal within the identified region of the coverage area.
