Abstract

Oggetto dell'invenzione è un sistema di rivelazione di errori (300; 500; 826) per ricevitore discreto (640). Il sistema di rivelazione di errori (300; 500; 826) indica i quadri cattivi del segnale di informazione binario che contengono dei bit affetti da distorsioni in numero eccessivo, così grande da provocare il fatto che un decodificatore convoluzionale (312; 512; 712) generi un segnale decodificato non corretto. Un segnale decodificato da un decodificatore convoluzionale (312; 512; 712) viene ricodificato da un codificatore (324; 524; 724) ed il segnale ricodificato viene confrontato (356; 556; 756) con il segnale ricevuto dal ricevitore (640). Quando un numero eccessivo di porzioni del segnale ricodificato differiscono in misura troppo notevole dalle corrispondenti porzioni di un segnale effettivo ricevuto, viene generata una indicazione di quadro cattivo.
