RECEPTION DEVICE, INTEGRATED CIRCUIT, AND RECEPTION METHOD

摘要

An OFDM demodulation section (13) converts a transmission signal of a time domain into a demodulation vector (Y) of a frequency domain. An equalization section (14) estimates a transmission line response vector (H') on the basis of the demodulation vector (Y) and equalizes the demodulation vector (Y) to calculate an equalization vector (X') on the basis of the estimated transmission line response vector (H'). An interference eliminating section (15) calculates an error component vector indicating an error component related to the interference between symbols and interference between carriers on the demodulation vector (Y) on the basis of the equalization vector (X') and the transmission line response vector (H') and eliminates the error component vector from the demodulation vector (Y) to generate and output a demodulation vector (Y').
