ABSTRACT:
Described is a transmission system for transmitting a multicarrier signal from a transmitter (10) to a receiver (20). The multicarrier signal comprises a plurality of subcarriers. The receiver (20) comprises a channel estimator (28) for estimating amplitudes of the subcarriers and for estimating time derivatives of the amplitudes. The receiver (20) further comprises an equalizer (24) for canceling intercarrier interference included in the received multicarrier signal in dependence on the estimated amplitudes and derivatives (29). The channel estimator (28) and/or the equalizer (24) are arranged for exploiting an amplitude correlation between the derivitives of different subcarriers. By making use of this correlation the complexity of the receiver (20) can be substantially reduced.
