Abstract

Procedimento per ricevere dati trasmessi in radiocomunicazioni del modo a treni di impulsi (burst) come GSM. Prima della trasmissione, un insieme di primi elementi di dati (bit) relativi ad un primo messaggio che può essere associato con un primo tipo di canale (ad esempio un canale di traffico (TCH) in GSM a bit selezionati sostituiti o "sottratti" da elementi di dati (bit) relativi ad un secondo messaggio che può essere associato con un secondo tipo di canale (ad esempio un canale associato veloce FACCH in GSM). Gli elementi di dati relativi al primo e secondo messaggi sono intercalati sul medesimo o su un diverso numero di treni di impulsi o burst. In un normale treno di impulsi di traffico GSM, due identificatori a bit singoli sono impostati a '1' per indicare rispettivamente quando i bit pari o i bit dispari del treno di impulsi o catena di dati chiusi (burst) sono stati sottratti per dati FACCH. Un rivelatore (5) è impiegato per sorvegliare gli identificatori dal medesimo numero di burst su cui i dati FACCH sono intercalati. Al fine di migliorare la possibilità di rivelare un FACCH in condizioni rumorose, è impiegato un circuito (9) di votazione di maggioranza tramite il quale decodificazione di FACCH è avviata se il numero di identificatori rivelati impostati a '1' supera un valore di soglia. Specificatamente, nel caso di FACCH, il valore di soglia può essere 5-8, cioè superiore a metà del numero di burst su cui i dati FACCH sono intercalati.
