RECEPTION DEVICE, INTEGRATED CIRCUIT, AND RECEPTION METHOD

摘要

An OFDM demodulation unit 13 transforms transmission signals in the time domain into demodulation vectors Y in the frequency domain; an equalization unit 14 estimates channel response vectors H′ based on the demodulation vectors Y, and calculates equalization vectors X′ by equalizing the demodulation vectors Y based on the estimated channel response vectors H′; and an interference removal unit 15 calculates error component vectors indicating error components pertaining to ISI and ICI related to the demodulation vectors Y, based on the equalization vectors X′ and the channel response vectors H′, generates demodulation vectors Y′ by removing the error component vectors from the demodulation vectors Y, and outputs the generated demodulation vectors Y′.
