摘要：
An apparatus and method for transmitting and receiving data having a smallest PAPR in an SLM scheme for PAPR reduction in an OFDM communication system using multiple carriers. To transmit the data having the smallest PAPR, input symbol sequences are duplicated to a plurality of data blocks. Phase-rotated data blocks are generated by multiplying the plurality of data blocks by different phase sequences. Side information for identifying the phase-rotated data blocks is inserted into a predetermined t position of the phase-rotated data blocks. IFFT is performed on the data blocks containing the side information. The data block having the smallest PAPR is selected among the inverse fast Fourier transformed data blocks.
