Title:
低減された複雑性のキャリア間干渉除去
Document Type and Number:
Japanese Patent JP4164363
Kind Code:
B2
Abstract:
Described is a transmission system for transmitting a multicarrier signal from a transmitter ( 10 ) to a receiver ( 20 ). The receiver ( 20 ) comprises an equalizer ( 24 ) for canceling intercarrier interference which may be included in the received multicarrier signal. The equalizer ( 24 ), which preferably is a MMSE equalizer, comprises a reduced complexity filter for deriving a vector of estimated symbols ( 25 ) from a vector of received symbols ( 23 ). The reduced complexity filter comprises a multiplication of an approximation of an inverse matrix R-1 with the vector of received symbols ( 23 ). The approximation of the inverse matrix R-1 is preferably a first order approximation.
