Abstract
In this article, a new scheme consisting of a combination of adaptive modulation, orthogonal frequency division multiplexing (OFDM), high order space-frequency block coding (SFBC), and antenna selection is presented. The proposed scheme, exploits the benefits of space-frequency block codes, OFDM and adaptive modulation to provide high quality of transmission for wireless communications over frequency selective fading channels. We examine the spectral efficiency and coding gain advantages of the proposed system. It is shown that antenna selection with adaptive modulation can greatly improve the performance of the conventional SFBC-OFDM systems.
