  • Method and system for synchronizing mutually interfering signals in digital radio transmissions with frequency re-use
    Patent number: 5327093
    Abstract: The present invention concerns a method and a system for demodulating mutually interfering signals according to a suitable synchronism bond between said signals. With such a system a complete decoupling of the demodulators of said signals is obtained. The system is characterized in that on each polarization there is at least a pair of demodulators, a first pair operate a baseband conversion of both signal H and V using the carrier recovery circuit driven by data of one of the two signals (e.g. V) and a second pair operate still a baseband conversion of both signals H and V but using said carrier recovery circuit now driven by data of the other signal (e.g. H).
