Abstract

Un transmisor transmite los datos que usan los símbolos de División de Frecuencia Ortogonal, OFDM. El transmisor que comprende un codificador de corrección de error delantero configurado para codificar los datos para formar los cuadros codificados de corrección de error delantero o de avance de las células de datos codificados, un constructor de cuadro de servicio configurado para formar un cuadro de servicio para la transmisión que comprende una pluralidad de cuadros codificados de corrección de error delantero, un intercalador convolucional comprendiendo una pluralidad de porciones de retraso y configurado para intercalar convolucionalmente las células de datos de los cuadros de servicio, un asignador del símbolo de modulación configurado para asignar las células de datos codificadas e intercaladas de los cuadros de servicio sobre las células de modulación, y un modulador configurado para modular los sub-portadores de uno o más símbolos OFDM con las células de modulación. Un controlador está configurado para formar los datos de señalización para ser transmitidos incluyendo una indicación de una primera célula identificada de uno de los primeros cuadros de corrección de error delantero o de avance de un nuevo cuadro de servicio que puede ser decodificado a partir de las células recibidas desde el nuevo cuadro de servicio, o el nuevo cuadro de servicio y uno más de los cuadros de servicio que siguen después del nuevo cuadro de servicio. Por la detección de la primera célula de uno de los primeros cuadros codificados de corrección de error de un nuevo cuadro de servicio que no tiene ninguna célula de datos en uno o más cuadros de servicio previo como un resultado de la intercalación convolucional luego un receptor, que ha adquirido el nuevo cuadro de servicio pero ninguno de uno o más de los cuadros de servicio previo puede decodificar este primer cuadro codificador de corrección de error delantero o de avance del nuevo cuadro de servicio e ignorar los otros cuadros codificados de corrección de error delantero antes en el cuadro de servicio. Por consiguiente, por ejemplo un receptor puede energizar o activar los canales durante, el cuadro de servicio previo y ser dirigido para solo decodificar un cuadro codificado de corrección de error delantero o de avance que puede decodificar.
