Fading doppler frequency estimation device and fading doppler frequency estimation method

A fading Doppler frequency estimation device comprising:

• a channel estimator that, based on the received signal received through a radio channel, estimates an estimated value of a channel showing channel characteristics of the radio channel;
• a correlation value calculator that calculates a time domain channel correlation value showing the time correlation of the radio channel, based on the estimated value of the channel;
• a channel power calculator that calculates channel power as the power of the received signal, based on the estimated value of the channel;
• a noise power calculator that calculates noise power as the power of the noise component contained in the received signal;
• a corrector that corrects 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;
• and,
• a fading Doppler frequency estimator that estimates the fading Doppler frequency based on the corrected time domain channel correlation value.
