After analyzing the ICI caused by high speed mobile channels using a simple curve fitting technique,the weighting factor for group transmission is optimized.Then,a new MIMO-OFDM technique,based on the weighting factor optimization,is proposed for reducing ICI caused by time varying channels.Performances of the proposed technique is verified by using the I-METRA channel,proposed for an MIMO channel to 3GPP,and an MIMO-OFDM simulator designed for macrocelluar mobile communication.It is shown by computer simulation that the proposed MIMO-OFDM technique is effective in reducing ICI and noise as well as in obtaining diversity gain even under highly-correlated fast fading channels,compared with the conventional MIMO-OFDM schemes.</p><p>IndexTerms—MIMO-OFDM,ICI,time-varying channel.</p><br/>
