PROBLEM TO BE SOLVED: To accurately estimate reception power at an arbitrary point, without inputting layout or quality of material of an obstruction such as furniture.SOLUTION: A reception power estimation device 100 comprises: a delay profile estimation unit 101 for estimating a delay profile on the basis of reception power of a plurality of paths actually measured in a space including an indoor space in which an obstruction is provided; a path transmission loss extraction unit 102 for calculating a transmission loss for each path on the basis of the estimated delay profile and reception power of the path in the case of assuming that the space is a free space; a mesh transmission loss estimation unit 104 which divides the indoor space into meshes and calculates an estimation value of a transmission loss for each mesh on the basis of the calculated transmission loss for each path; and a reception power estimation unit 105 for calculating an estimation value of reception power at an arbitrary point in the space, on the basis of the estimation value of the transmission loss value for each mesh. |
