Abstract:
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 â€œNâ€  or less orthogonal multiple carriers, where â€œNâ€  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 â€œMâ€  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 â€œNâ€  or less orthogonal multiple carriers spaced at M-carrier intervals, where â€œMâ€  denotes a predetermined natural number equal to or greater than 2.
