PROBLEM TO BE SOLVED: To provide a receiving device, a receiving method, and a receiving program, capable of significantly improving propagation path estimation accuracy in radio communication.SOLUTION: A GI removal unit b102-nremoves GI from a received signal. An FFT unit b103-nconverts a time frequency with respect to a signal obtained by a step S101. A demapping unit b104-nseparates received signals of the resource elements to which data, a first pilot symbol, and a second pilot symbol were transmitted from signals of the frequency region to be obtained. A path extraction unit b105-nextracts a path effective for estimation using the first pilot symbol. A propagation path estimation unit b106-ncalculates a first CFR estimate using the second pilot symbol, calculates a CIR estimate using the path position information extracted by the path extraction unit and the first CFR estimate, and then converts the CIR estimate to a second CFR estimate. |
