SEQUENCE MULTIPLEXING TRANSMITTING/RECEIVING METHOD FOR IMPROVING PEAK-TO-AVERAGE POWER RATIO IN ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING METHOD

摘要

The sequence multiplex transceiving method for reducing the PAPR (Peak-to-Average Power Ratio) is provided to obtain the high PAPR reduction efficiency in case a small amount of dummy sequence is inserted. The input entry sequence is successively inputted. The length information of set up one or more redundant bit is inputted in advance(S210). The length information of the redundant bit is the bit number of the redundant bit. The input entry sequence comprises the length information of the redundant bit. The input entry sequence is transformed to the input data sequence of the parallel configuration(S220). The half repair high speed inverse fourier input data sequence is produced by performing the XOR (Exclucive OR) computing on the transformed input data sequence and redundant bit (S230). The length of the computed redundant bit and length information of the set-up redundant bit are compared (S240). The half repair high speed inverse fourier input data sequence is computed by the half repair high speed inverse fourier(S250). The OFDM signal is generated by changing sequence to the serial type.
