Abstract:
Provided is an orthogonal frequency division multiplexing (OFDM) apparatus using a 3-dimensional (3D) signal constellation. The apparatus performs 2D inverse fast Fourier transform on a set of 3D subchannel signals that is mapped by a signal constellation including signal points distributed on the surface of a 3D sphere.
