Abstract

Method and apparatus for frequency and phase synchronization between radio transmitters interconnected via cable and/or radio, characterized in that each assisted transmitter emits signals with equal frequency and with a phase relation with respect to those received from the main transmitter as consequence of a comparison made respectively between the output signals of the oscillator of the assisted transmitter and the arrival signals from the main transmitter and of a frequency and phase correction of the output signals from the oscillator of the assisted transmitter that reduces to zero the difference of the respective frequencies and the predetermined value and constant the difference of the respective phases.
