Abstract

UN METODO Y UN SISTEMA (16) POR EL QUE LOS DATOS DE UN PARAMETRO REPRESENTATIVO DEL LENGUAJE CODIFICADO SE ORGANIZAN EN PAQUETES DE DATOS PARA LA TRANSMISION, REDUCIENDO ASI EL IMPACTO DE LOS ERRORES INDUCIDOS SOBRE EL PAQUETE DE DATOS EN EL CANAL DE TRANSMISION. UN PAQUETE DE DATOS SE CONSTRUYE CON CIERTA MAYORIA DE BITIOS PERCEPTIBLEMENTE SIGNIFICANTES DE LOS DATOS DEL PARAMETRO EN EL PRINCIPIO DEL PAQUETE DE DATOS. LO SIGUIENTE EN EL PAQUETE DE DATOS SON MENOS BITIOS PERCEPTIBLEMENTE SIGNIFICANTES DEL MISMO DATO DEL PARAMETRO. OTRO DATO DE PARAMETRO SIGUE DESPUES EN EL PAQUETE DE DATOS. INTERCALADO EN EL PAQUETE DE DATOS SIGUE LA MAYORIA DE BITIOS PERCEPTIBLEMENTE SIGNIFICANTES DEL PRINCIPIO DEL PAQUETE DE DATOS, QUE SON LA MAYORIA DE BITIOS PERCEPTIBLEMENTE SIGNIFICANTES DE OTRO DATO DE PARAMETRO. UN CODIGO DE COMPROBACION DE PARIDAD SE PROCESA DESDE LA MAYORIA DE BITIOS PERCEPTIBLEMENTE SIGNIFICANTE EN EL PAQUETE DE DATOS Y TAMBIEN INTERCALADO EN EL PAQUETE DE DATOS SIGUE LA MAYORIA DEBITIOS PERCEPTIBLEMENTE SIGNIFICANTE DEL PRINCIPIO DEL PAQUETE DE DATOS.
