METHOD AND APPARATUS FOR SYNCHRONIZING SIMULCAST SYSTEMS

摘要

A method for measuring a time delay between a controller (302) and a plurality of base sites (306) in a simulcast system (300). The method begins with the controller (302) transmitting a first signal to one of the plurality base sites (306A) and transmitting a second signal at substantially the same time to a delay monitor (316) that receives the second signal and a third signal from a selected base site (306A). The delay monitor (316) transmits the time between the transmission and reception of the first signal to the controller (302) whichprograms the base sites (306) to delay transmissions of the RF signals in response to the measured delay.
