The Adaptive Modulation (AM) for Space-Time Block Code OFDM (STBC-OFDM) is addressed in this article as application for wireless systems. A new method was proposed, which is used the dispersion of Error Vector Magnitude (EVM) to represent the current channel condition in the following frames and to select the appropriate Modulation Scheme (MS) for the subsequent frame. In this method, the AM is not only compensated the channel variation, but also guaranteed the required Bit Error Rate (BER) performance and maximized the Spectral Efficiency (SE). The simulation shows that the proposed scheme outperforms in gaining performance the conventional scheme for all MS over a fading channel.
