Abstract

Recently, time-frequency interferometry (TFI)-OFDM has been proposed as a channel identification scheme.TFI-OFDM system can multiplex the same impulse response in twice on the time domain without overlapping to each other. Moreover, by averaging of these impulse responses, the accurated channel impulse responses are obtained. However, under the fast fading channel, the change of channel conditions is too fast to be followed by channel estimator in. the receiver. Therefore, too many errors occur in data demodulation processing particularly in the last part of data symbols. To overcome this problem, in this paper, we propose the decision direct and linear prediction based fast fading compensation method for TFI-OFDM.
