OFDM reception apparatus

摘要

The OFDM reception apparatus includes: a channel response calculation section for determining channel responses for pilot carriers; and an adaptive filter. The adaptive filter receives a first channel response for a first pilot carrier and a second channel response for at least one second pilot carrier at a same symbol, and repeats performing predetermined computation for the second channel response and updating a coefficient used in the computation so that the computation result is closer to the first channel response. Also, once the final value of the coefficient is determined, the adaptive filter performs the predetermined computation for a channel response at a selected pilot carrier frequency of the same number as the number of the at least one second pilot carrier at the same symbol as the second channel response, and outputs the computation result.
