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 translation: 提供了一种正交频分复用（OFDM）传输系统，其包括：数据处理单元，其使用包括保留音的多个音调生成发送信号;存储单元，其根据数据符号的类型存储峰值减少内核信息; 以及补偿单元，其根据来自存储单元的数据符号的类型检索峰值降低内核信息，并且使所检索的信息由包含在发送信号中的保留的色调承载。 因此，可以有效地补偿峰均功率比（PAPR）。
