<p>PROBLEM TO BE SOLVED: To evaluate channel information acquired from a receiving signal whose reception quality is degraded.SOLUTION: The communication apparatus has: a channel information estimation section which estimates channel information on a frequency axis on the basis of a reference signal included in a signal which is received between a base station and a terminal device; a time-axis channel information estimation section which acquires an impulse response on the time-axis on the basis of the reference signal included in the received signal and the reference signal which is stored in advance; and a channel information management section which stores the channel information as transmission path characteristics between the terminal device and the base station corresponding to the channel information when the impulse response satisfies a predetermined standard, and stores a predetermined value as transmission path characteristics between the terminal device and the base station corresponding to the channel information when the impulse response does not satisfy a predetermined standard.</p> |
