Abstract
A system and method for determining a signal propagation delay between a transmitter and a receiver, and for adjusting a transmission time based on the propagation delay. A central station inserts a marker into a transmitted signal at a time corresponding to a received timing signal. The MCT receives the signal from the central station and determines a time difference between receipt of the marker and the detection of the time interval event. A transmission by the MCT is adjusted by an amount of time proportional to the time difference.
