摘要

PROBLEM TO BE SOLVED: To provide a receiving device capable of estimating a propagation path with a high degree of accuracy.

SOLUTION: The receiving device comprises a propagation path estimation part (b106) which estimates a propagation path. The propagation path estimation part comprises: a temporary channel impulse response estimation part (b106-1) which calculates a temporary channel impulse response estimation value; a path extraction part (b106-3) which extracts a path used for calculating a channel impulse response estimation value among the paths constituting the temporary channel impulse response estimation value; a channel impulse response estimation part (b106-4) which calculates the channel impulse response estimation value using the path extracted by the path extraction part; and a frequency response estimation part (b106-5) which performs a time frequency conversion to the channel impulse response estimation value to convert it into a frequency response estimation value.
