  • Method for the fast synchronization of vocoders coupled to one another by enciphering
    Patent number: 4964165
    Abstract: A method for the fast synchronization of vocoders, coupled to each other by means of enciphering and deciphering devices, consists in synchronizing the data frames transmitted by the vocoders with the end of the sequence for synchronizing the enciphering and deciphering devices, in transmitting the decryption data for a period equal to a whole multiple of the duration of a digital frame of speech data transmitted and in synchronizing the called vocoder with the end of transmission of the decryption data. Thus, a gain is obtained in the synchronization acquisition time.
