Abstract
In time varying OFDM systems, the effect of a non-ideal time synchronization may lead to a poor performance in terms of decoded average bit error rate versus the signal-to-noise ratio. The receiver apparatus () of the transmission system () estimates a subcarrier-dependent channel frequency response and determines an intercarrier interference spreading on the basis of a cyclic shift in symbols carried by the subcarriers. Therewith, an intercarrier interference included in an OFDM signal can be canceled, even in case of a non-ideal time synchronization.
