Abstract
Channel estimator, based on the received signal received through a radio channel, estimates an estimated value of a channel showing channel characteristics of the radio channel. Correlation value calculatorcalculates a time domain channel correlation value showing the time correlation of the radio channel, based on the estimated value of the channel. Channel power calculatorcalculates channel power as the power of the received signal, based on the estimated value of the channel. Noise power calculatorcalculates noise power as the power of the noise component contained in the received signal. Correctorcorrects the channel power based on the noise power and corrects the time domain channel correlation value based on the corrected channel power and the noise power. Fading Doppler frequency estimatorestimates the fading Doppler frequency based on the corrected time domain channel correlation value.
