Reduced complexity intercarrier interference cancellation |
摘要 |
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.
