- 초록
- In this paper, a three-dimensional (3-D) orthogonal frequency division multiplexing (OFDM) is introduced. In the new OFDM, a 3-D signal mapper and 2-D inverse discrete Fourier transform are used to allocate 3-D signals to OFDM subchannels and to modulate the signals, respectively. The minimum Euclidean distance of the 3-D signal mapper is much farther than that of the 2-D mapper if both mappers are normalized to have the same average power. As a result, the proposed OFDM has much improved error performance as compared with the conventional scheme. ©2009 IEEE.
