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 8):
The wireless reception device according to  claim 7 , wherein\n the transmission line calculation unit includes:\n an averaging sample-sequence generation unit that outputs a sample sequence including samples whose number agrees with number of samples of the delay profile outputted by the delay profile calculation unit; \n a time domain averaging sample-sequence generation unit that inputs the sample sequence outputted by the averaging sample-sequence generation unit, and generates a time domain averaging sample sequence by carrying out an Inverse Fourier Transform process to the inputted sample sequence; \n a time domain averaging sample-sequence combination unit that inputs the time domain averaging sample sequence from the time domain averaging sample-sequence generation unit, inputs the division point from the delay profile division unit, inputs the path position from the path detection unit, and calculates a combined time domain averaging sample sequence by using the inputted values; \n an averaging weight-coefficient calculation unit that inputs the combined time domain averaging sample sequence from the time domain averaging sample-sequence combination unit, and that calculates an averaging weight coefficient by using the combined time domain averaging sample sequence which is inputted; and \n a weighted averaging processing unit that inputs the transmission line estimation result from the reference multiplication unit, inputs the averaging weight coefficient from the averaging weight-coefficient calculation unit, assigns the inputted weight coefficients to the samples whose number agrees with number of averaging samples, and calculates the transmission line calculation result by carrying out averaging among the weighted samples which are adjacent each other.
