Title:
OFDM受信機
Document Type and Number:
Japanese Patent JP4291673
Kind Code:
B2
Abstract:
An OFDM receiver receives an OFDM signal transmitted from an OFDM transmitter by using a sub-carrier. The OFDM receiver includes a channel estimator configured to obtain a channel estimated value of each multi-path based on OFDM signals received through a plurality of multi-paths; a transmission signal estimated value calculator configured to calculate a transmission signal estimated value as an estimated value of the OFDM signal; and an inter-carrier interference compensator (400) configured to extract a multi-path not becoming a form to contain a signal component only of a target symbol in an FFT window based on the transmission signal estimated value and the channel estimated value of each multi-path, and to compensate for inter-carrier interference in the OFDM signal based on signal components corresponding to all sub-carriers of the multi-paths.
