Abstract

La presente invenzione riguarda un metodo ed un sistema per la demodulazione di segnali mutuamente interferenti secondo un opportuno vincolo di sincronismo tra detti segnali. Con tale sistema si ottiene un completo disaccoppiamento dei demodulatori di detti segnali. Il sistema si caratterizza per il fatto che su ogni polarizzazione c'è almeno una coppia di demodulatori, una prima coppia opera convertendo in banda base entrambi i segnali H e V utilizzando il detto circuito di recupero della portante pilotato tramite i dati di uno dei due segnali (ad esempio V) una seconda coppia opera convertendo ancora in banda base entrambi i segnali H e V ma utilizzando il detto circuito di recupero della portante pilotato ora dai dati dell'altro segnale (ad esempio H).
