Abstract
Un método para transmision de datos en una disposicion de emision de audio digital incluye las etapas de proporcionar una pluralidad de sub-portadoras multiplexadas por division de frecuencia ortogonal, incluyendo las sub-portadoras, sub-portadoras de datos y sub-portadoras de referencia, y modular las sub-portadoras de datos con una senal digital representativa de informacion a ser transmitida. Las sub-portadoras de referencia son moduladas por una secuencia de bits de cronizacion, en la que la secuencia de bits de cronizacion incluye una palabra de sincronizacion de bloques inequívoca, y la cantidad de bits que comprende la palabra de sincronizacion de bloques es menor de una mitad de la cantidad de bits en dicha secuencia de cronizacion. . Después las sub-portadoras multiplexadas por division de frecuencia ortogonal son trasmitidas. También se incluyen receptores que detectan diferencialmente la palabra de sincronizacion de bloques y utilizan la palabra de sincronizacion de bloques p ara detectar coherentemente la senal digital representativa de informacion a ser transmitida.
