OFDM transmitting and receiving systems and methods thereof

The OFDM transmission system is disclosed. The system, by using a plurality of tones including a reserved tone, a reduction peak corresponding to each data processor, a data symbol type for generating a transmission signal kernel (Peak Reduction Kernel) information corresponds to the stored storage unit and transmit the type of data symbols determine the peak reduction kernel from the storage unit to be put in reserve comprises a compensation tones in a transmission signal. As a result, PAPR can be effectively compensated. OFDM, PAPR, peak reduction kernel, a storage unit
