Multicarrier receiver with channel estimator |
摘要 |
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.
