Abstract

SE PRESENTA UN METODO PARA GENERAR UNA CORRIENTE DE BITS MULTIPLEXANDO INFORMACION AUXILIAR NO COMPRIMIDA CON UNA CORRIENTE DE INFORMACION. LA CORRIENTE DE INFORMACION SE OBTIENE COMPRIMIENDO UNIDADES DE TAMAÑO FIJO DE UNA SEÑAL DE INFORMACION CON PROPORCIONES DE COMPLEXION VARIABLES PARA SUMINISTRAR UNIDADES DE TAMAÑO VARIABLE DE LA CORRIENTE DE INFORMACION. LA INFORMACION AUXILIAR ESTA DISPUESTA PARA SU USO EN LA DESCODIFICACION SUBSECUENTE DE LA CORRIENTE DE INFORMACION. LAS UNIDADES DE INFORMACION AUXILIAR SE CORRESPONDEN CON LAS UNIDADES DE LA SEÑAL DE INFORMACION. EN EL METODO, LA CORRIENTE DE INFORMACION SE DIVIDE EN PERIODOS DE TIEMPO EN POSICIONES DE CORRIENTE DE INFORMACION. LA INFORMACION AUXILIAR NO COMPRIMIDA TAMBIEN SE DIVIDE EN TIEMPO EN PARTES DE INFORMACION AUXILIAR. LAS PARTES DE LA CORRIENTE DE INFORMACION Y LAS PARTES DE INFORMACION AUXILIAR SE INTERCALAN PARA SUMINISTRAR LA CORRIENTE DE BITS. FINALMENTE, LA DIVISION DE LA CORRIENTE DE INFORMACION, LA DIVISION DE LA INFORMACION AUXILIAR Y LOS PASOS DE INTERCALACION SON CONTROLADOS EMULANDO LA DESCODIFICACION DE LA CORRIENTE DE BITS MEDIANTE UN DESCODIFICADOR DE SISTEMA HIPOTETICO. EL DESCODIFICADOR DE SISTEMA HIPOTETICO INCLUYE UN MULTIPLEXOR QUE DESMULTIPLEXA LA CORRIENTE DE BITS, UN DISPOSITIVO SERIE DE UN BUFFER DE CORRIENTE DE INFORMACION Y UN DESCODIFICADOR DE CORRIENTE DE INFORMACION, Y UN DISPOSITIVO SERIE DE UN BUFFER DE INFORMACION AUXILIAR Y DE UN PROCESADOR DE INFORMACION AUXILIAR. CADA DISPOSITIVO SERIE ESTA CONECTADO AL DESMULTIPLEXOR. LA DIVISION DE LA CORRIENTE DE INFORMACION, LA DIVISION DE LA CORRIENTE AUXILIAR Y LOS PASOS DE INTERCALACION SON CONTROLADOS DE MANERA QUE EL BUFFER DE LA CORRIENTE INFORMACION Y EL BUFFER DE LA INFORMACION AUXILIAR NO SUFRAN DESBORDAMIENTOS.
