摘要

In a receiving apparatus (100), a noise power estimation unit (107) estimates the noise power included in a received signal in the frequency domain. A channel characteristics calculation unit (105) estimates the channel characteristics in accordance with a reference signal included in the received signal. A tap coefficient calculation unit (108) calculates the tap coefficients for a filtering unit (109) in accordance with noise power included in the received signal and with an autocorrelation value for the channel characteristics. The filtering unit (109) calculates an estimated value for the channel characteristics via filtering processing on the channel characteristics in accordance with the tap coefficients.
