Abstract
In order to improve accuracy in estimating a transmission line that includes a delay path having a long delay time, the present invention provides a wireless reception device that includes a transmission estimation unit including: a delay profile generation unit that estimates a transmission line from a reference signal portion by using a known reference signal replica, and that calculates a delay profile from a transmission line estimation result; a path detection unit that detects a position of a sample, which is included in the delay profile, as a path position; a delay profile division unit that divides the delay profile based on the path position; and a transmission line calculation unit that calculates a transmission line per path by carrying out averaging to the delay profile per path in the frequency domain, and that combines transmission line calculation results per path.
