Adaptive modulation for space–frequency block coded OFDM systems
M Torabi - AEU-International Journal of Electronics and …, 2008 - Elsevier
The growing popularity of both multiple-input multiple-output (MIMO) and orthogonal
frequency division multiplexing (OFDM) systems has created the need for adaptive
modulation to integrate temporal, spatial and spectral components together. In this article, an
overview of some adaptive modulation schemes for OFDM is presented. Then a new
scheme consisting of a combination of adaptive modulation, OFDM, high-order space-
frequency block codes (SFBC), and antenna selection is presented. The proposed scheme …
