OFDM APPARATUS USING THREE-DIMENSIONAL HEXADECIMAL SIGNAL CONSTELLATION

摘要

A three-dimensional OFDM apparatus of the present invention comprises: a serial-parallel conversion unit for converting a serial input signal into N parallel input signals; a three-dimensional signal mapping unit for mapping the N parallel input signals on three-dimensional coordinates of a cube-in-cube type constellation, respectively; and a two-dimensional inverse Fourier transform unit for performing an inverse Fourier transform by generating a two-dimensional matrix on the basis of the mapped three-dimensional coordinates.
