A novel transmission scheme called time-frequency training OFDM (TFT-OFDM) is presented, whereby time-domain training sequence and frequency-domain grouped pilots are used for the joint time-frequency channel estimation. The pilots only occupy about 1% of the used subcarriers, and the complex interference cancellation could be avoided. As a result, TFT-OFDM simultaneously achieves high spectral efficiency and reliable performance over fast fading channels.
