Abstract

SE PROPONE UN SISTEMA DE CODIFICACION DE DATOS EN EL CUAL UNA CORRIENTE DE BITS DE UNA VELOCIDAD BAJA (AUX) SE CODIFICA JUNTO CON UNA CORRIENTE DE BITS PRINCIPAL DE ALTA VELOCIDAD (PRIM) SIN INCREMENTAR LA VELOCIDAD DE LA TRANSMISION POR ENCIMA DE LA VELOCIDAD ALTA. ESTA CORRIENTE AUXILIAR DE BITS (AUX) SE TRANSMITE DE FORMA SINCRONICA CON LA CORRIENTE PRINCIPAL DE BITS (PRIM). PARA CONSEGUIR ESTO, EL TRANSMISOR (T) DIVIDE LA CORRIENTE PRINCIPAL DE BITS EN BLOQUES QUE SE PRODUCEN DE FORMA PERIODICA DE Y BITS Y CODIFICA UN BIT DE LA CORRIENTE AUXILIAR DE BITS (AUX) EN CADA UNO DE DICHOS BLOQUES USANDO UNA PRIMERA LEY DE CODIFICACION (AMI) O UNA SEGUNDA LEY DE CODIFICACION (VAMI) DE ACUERDO CON EL VALOR BINARIO DE ESE BIT. LA SEGUNDA LEY SE CONSTRUYE VIOLANDO LA PRIMERA LEY DE CODIFICACION DE ACUERDO CON UNA LEY DE VIOLACION PREDETERMINADA. LA REDUNDANCIA EN LA PRIMERA LEY DE CODIFICACION SE USA PARA INTRODUCIR SECUENCIAS DE SIMBOLOS NO PERMITIDAS BAJO ESTA PRIMERA LEY DE CODIFICACION (AMI) YDE ESTA FORMA PARA OBTENER LA SEGUNDA LEY DE CODIFICACION (VAMI).
