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 6):
The wireless reception device according to  claim 1 , comprising:\n a delay profile rotation unit that inputs the delay profile per path from the delay profile division unit, and removes phase rotation by rotating the delay profile based on the path position in such a way that path timing of the delay profile per path become zero timing; a Fourier Transform unit that inputs the delay profile per path from which the phase rotation is removed by the delay profile rotation unit, and carries out Fourier Transform to the delay profile per path from which the phase rotation is removed; an averaging processing unit that inputs an output signal of the Fourier Transform unit, and that carries out a frequency domain averaging process to the output signal of the Fourier Transform unit; a phase multiplication unit that inputs an output signal of the averaging processing unit, inputs the path position from the path detection unit, and calculates the transmission line calculation result per path by multiplying the output signal of the averaging processing unit by a phase which cancels the rotation carried out by the delay profile rotation unit based on the path position; and a combination unit that inputs the transmission line calculation result per path from the phase multiplication unit, and combines all of the transmission line calculation results per path.
