Abstract

Se describe un dispositivo de transmisión del tipo OFDM que comprende los medios para crear un canal de unidifusión, medios para crear un canal MBMS, los medios para la multiplexión en el tiempo del canal de unidifusión y el canal MBMS con una banda de frecuencia común, y los medios para enviar un símbolo de transmisión multiplexado en el tiempo. La longitud de intervalo de protección para el canal MBMS es ajustada más grande que la longitud del intervalo de protección para el canal de unidifusión.
