ZIONE DI ERRORI CAUSATI DA RUMORE METODO E DISPOSITIVO PER LA CORREDI TIPO IMPULSIVO SU SEGNALI VOCALI CODIFICATI CON BASSA VELOCITA DI CIFRA E TRASMESSI SU CANALI DI COMUNICAZIONE RADIO

摘要

In a radio transceiving system of low bit-rate coded speech signals, to be installed on mobiles, the method allows the detection and correction of burst error present in the demodulated coded signal, in the receiver. This method allows error detection by distance measurements among the values of the decoded parameters in subsequent intervals and, in case of error, to substitute values obtained with linear-interpolation techniques for the erroneous parameters.
