Abstract

The increasing need of high data rate transmissions over fading channels has drawn attention to modulation schemes with high spectral efficiency such as the multidimensional rotated MPSK/QAM constellations. A novel coding-rotated-modulation OFDM (orthogonal frequency division multiplexing) scheme is proposed. The new scheme takes full advantage of the modulation diversity of rotated MPSK/ QAM (quadrature amplitude modulation), the frequency diversity of OFDM system and the coding-gain of Turbo codes all together. Simulation results have turned out this new scheme can significantly outperform the conventional BICM (bit-interleaved coded modulation)-OFDM scheme.
