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.

Claim (Index 1):
A wireless reception device, comprising:\n a transmission line estimation unit including:\n a delay profile generation unit that inputs a reference signal portion which is included in a reception signal converted into a frequency domain signal, and calculates a delay profile from a transmission line estimation result which is estimated based on the reference signal portion by using a known reference signal replica; \n a path detection unit that inputs the delay profile from the delay profile generation unit, and detects a position of a sample, which is included in the delay profile, as a path position; \n a delay profile division unit that inputs the delay profile from the delay profile generation unit, and inputs the path position from the path detection unit, and divides the delay profile per a path based on the path position; and \n a transmission line calculation unit that inputs the delay profiles per path into which the delay profile is divided by the delay profile division unit, calculates a transmission line per path by carrying out averaging to the delay profile per path in the frequency domain, and combines transmission line calculation results per path.
