  • Method of and device for correcting burst errors on low bit-rate coded speech signals transmitted on radio-communication channels
    Patent number: 4688224
    Abstract: 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.
