Abstract

Un transmisor que transmite datos de cara útiles utilizando símbolos (OFDM) Multiplexados de División de Frecuencia Ortogonal. El transmisor comprende un formador de tramas configurado para recibir los datos de carga útil para ser transmitidos y para recibir los primeros datos de señalización para el uso en la detección y recuperación de los datos de carga útil en un receptor, y para formar los datos de carga útil y los primeros datos de señalización en tramas para la transmisión, los primeros datos de señalización que forman una parte de las tramas con los datos de carga útil. Se configuró un modulador para modular un primer símbolo OFDM con los primeros datos de señalización y para modular uno o más de los segundos símbolos OFDM con los datos de carga útil. Un procesador de secuencia de firma proporciona una secuencia de firma, un combinador combina la secuencia de firma con el primer símbolo OFDM, y una unidad de transmisión transmite el primero y los segundos símbolos OFDM. La secuencia de la firma prevista por el procesador de secuencia de la firma que comprende al menos uno de una secuencia de sincronización o una segunda secuencia de mensaje, la primera secuencia de sincronización y/o la segunda secuencia de mensaje que se combinó por el combinador con el primer símbolo OFMD. La primera secuencia de sincronización se proporcionó para un receptor para detectar y recuperar los primeros datos de señalización de primer símbolo OFDM y la segunda secuencia del mensaje proporciona información del mensaje al receptor. La información del mensaje puede ser utilizada para comunicar un mensaje específico a un usuario tal como advertencia de emergencia por un desastre natural como un temblor o una advertencia de tsunami.
