1. A method comprising the steps of:

  • generating a first orthogonal-multi-carrier signal through N-point inverse discrete Fourier transform, the first orthogonal-multi-carrier signal having “

    N”

    or less orthogonal multiple carriers, where “

    N”

    denotes a predetermined natural number equal to or greater than 2; and

    repeating every 1-unit time segment of the first orthogonal-multi-carrier signal “

    M”

    times to generate every 1-symbol time segment of a second orthogonal-multi-carrier signal, the second orthogonal-multi-carrier signal having a thinned set of “

    N”

    or less orthogonal multiple carriers spaced at M-carrier intervals, where “

    M”

    denotes a predetermined natural number equal to or greater than 2.
