RECEIVER APPARATUS FOR RECEIVING A MULTICARRIER SIGNAL

摘要

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 (3) of the transmission system (1) 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.
