Abstract

METODO DE CODIFICACION Y CODIFICADOR DE VOZ PARA EQUIPOS Y SISTEMAS DE COMUNICACION, EN BASE A DIGITALIZAR LA VOZ A VELOCIDADES RELATIVAMENTE BAJAS MEDIANTE EL USO DE ALGORITMOS DE COMPRESION QUE PORPORCIONA UNA CALIDAD DE VOZ MUY ALTA PERMITIENDO IDENTIFICAR Y RECONOCER AL INTERLOCUTOR DEL EXTREMO REMOTO SIENDO LA COMUNICACION PROTEGIBLE MEDIANTE LA GESTION DE CLAVES CON PROCEDIMIENTOS COMPUTACIONALMENTE SEGUROS PUDIENDO CONFIGURARSE EL SISTEMA PARA FUNCIONAR COMO TELEFONO, COMO CENTRAL, O BIEN COMO CANAL DE AUDIO, COMPRENDIENDO LA CODIFICACION LAS ETAPAS DE ANALISIS, SELECCION Y SINTESIS, LAS CUALES SE REALIZAN EN UN CODIFICADOR DE VOZ QUE INCORPORA UN PROCESADOR RAPIDO DE TRATAMIENTO DIGITAL DE LA SETAL (DES), UN MICROCONTROLADOR (MC) JUNTO CON LA CIRCUITERIA DE CANCELAR POSIBLES ECOS EN LA COMUNICACION Y TRANSMITE EN MODO "MONOSINCRONO" Y SU SINCRONIZACION INTERNA ES DE EXTREMO-EXTREMO.
