| 摘要 |
A method of transmitting/receiving an OFDM signal and mobile communication terminal thereof are disclosed, by which high PAPR (peak to average power ratio) can be efficiently reduced in an OFDM transmission system. The present invention includes the steps of converting a bit stream data signal to parallel from serial, block-coding the paralleled data signal, Hadamard-transforming the block-coded data signal, performing IFFT (inverse fast Fourier transform) on the Hadamard-transformed data signal, and converting the IFFT-ed data signal from the parallel to the serial to transmit. |
