摘要： The present invention relates to a method for modulating a signal, which is a signal modulation method for data communication, and the method comprises the steps of: forming a data symbol sequence to which a symbol 0 having the overall length of N are added, by adding M-1 symbols 0 to each symbol of a data symbol sequence; performing an N-point fast Fourier transform for the data symbol sequence to which said symbols 0 are added; performing precoding for said fast-Fourier-transformed data symbol sequence; and forming a final transmission symbol sequence by performing an inverse fast Fourier transform for said precoded data symbol sequence. Further, the present invention relates to a transmitter which comprises: a symbol adding unit that forms a data symbol sequence to which the symbol 0 having the overall length of N is added, by adding M-1 symbols 0 to each symbol of a data symbol sequence; a fast Fourier transform unit that performs an N-point fast Fourier transform for the data symbol sequence to which said symbols 0 are added; a precoding unit that performs precoding for said fast-Fourier-transformed data symbol sequence; and an inverse fast Fourier transform unit that forms a final transmission symbol sequence by performing an inverse fast Fourier transform for said precoded data symbol sequence.
