    Abstract: An orthogonal frequency division multiplexing (OFDM) transmission system is provided which includes a data processing unit which generates a transmission signal using a plurality of tones including a reserved tone, a storage unit which stores Peak Reduction Kernel information according to the type of data symbol, and a compensation unit which retrieves the Peak Reduction Kernel information according to the type of data symbol from the storage unit and causes the retrieved information to be carried by the reserved tone included in the transmission signal. Therefore, a Peak-to-Average Power Ratio (PAPR) can be efficiently compensated.

    Abstract: A broadcast data transmission method includes generating service composition information of a broadcasting service to be provided using a broadcast packet transmitted through a frequency channel; generating first signaling information indicating an ensemble in which the service composition information is to be transmitted; and transmitting the broadcast packet, the service composition information, and the first signaling information. The service composition information may include at least one of a service identifier for the broadcasting service, genre information representing a genre of the broadcasting service, and information about a provider of the broadcasting service.
