PROBLEM TO BE SOLVED: To provide a radio propagation path evaluation device that can obtain high evaluation accuracy, even from many kinds of diversified temporal fluctuations in a radio propagation path. SOLUTION: This radio propagation path evaluation device, by which an evaluation value decision means acquires quality evaluation value of the radio propagation path, on the basis of a reception demodulation signal through at least one path obtained from a received radio signal, is characterized in the provision of a propagation path time fluctuation detection means, that obtains a propagation path time fluctuation parameter denoting temporal fluctuations in a radio propagation path state, on the basis of at least one received demodulation signal and with an observation period control means that changes the observation period of the received demodulation signal, when the evaluation value decision means decides the quality evaluation value, on the basis of at least the obtained propagation path time fluctuation parameter. |
