1. A method, performed by a transmission apparatus, of transmitting data in a wireless communication system, the method comprising:
performing π/2-binary phase shift keying (BPSK) modulation on M symbols;
performing a discrete Fourier transform (DFT) on the M symbols on which the π/2-BPSK modulation has been performed;
identifying M/2 symbols among the M symbols on which the DFT has been performed, wherein the M symbols on which the DFT has been performed are symmetric and information of the identified M/2 symbols is same with information of remaining M/2 symbols among the M symbols on which the DFT has been performed; wherein M is an integer greater than or equal to 1;
performing an inverse fast Fourier transform (IFFT) on the M/2 symbols identified among the M symbols on which the DFT has been performed; and
transmitting, to a reception apparatus, the M/2 symbols on which the IFFT has been performed,
wherein a constellation of the M symbols on which the π/2-BPSK modulation has been performed has only real components or imaginary components.
