The Zenith Scheme: A Novel Modulation Technique for MIMO OFDM Systems with 2D-FFT

In this paper, the Zenith scheme is proposed for MIMO OFDM systems, which modulates data on the 2-dimensional sinusoids. The Zenith scheme is an open-loop solution, but achieves better performance than the closed-loop solution in certain cases. Therefore, the Zenith scheme will likely add to the list of good options for data modulation in wireless networks.
