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 9):
The wireless reception device according to  claim 1 , comprising:\n a data demodulation unit that receives the reception signal, converts the reception signal of a time domain signal into a frequency domain signal, and outputs the reference signal portion, which is included in the reception signal converted into the frequency domain signal, to the transmission line estimation unit, inputs the transmission line calculation result from the transmission line estimation unit, and regenerates an original signal from a data signal portion, which is included in the reception signal converted into the frequency domain signal, by using the inputted transmission line calculation result.
