Abstract

PARA EL TRATAMIENTO DE DATOS EN PARTICULAR DE PARAMETROS DE SEÑALES DE VOCES PARA TRANSMISION EN CUOTA DE BIT REDUCIDA, SE ACOPLAN CONJUNTAMENTE PARAMETROS DE SEÑAL DEL MISMO TIPO DE FORMA CUANTIZADA EN SECCIONES. PARA CONSEGUIR UNA REDUCCION ADICIONAL DE BIT, LOS BITS SON PRESIONADOS A PARTIR DEL NUMERO TOTAL DE BITS DE AL MENOS DOS SECCIONES, AQUELLAS DONDE LA SUPRESION DIFERENCIAL DE BIT A PARTIR DEL NUMERO TOTAL DE BIT NO REDUCIDOS SE FORMA PARA OBTENER LA POTENCIA PROXIMA MAS ALTA DE DOS. EL PROCESO SUMINISTRA UNA MEJOR CALIDAD DE VOZ QUE CUANDO EL NUMERO DE ETAPAS DE CUANTIZACION SE CAMBIA MEDIANTE MULTIPLOS DE 2.
