Abstract
A radio wave propagation characteristic estimation system in a radio communication system includes: non-diffracted wave estimation device configured to estimate propagation characteristics of a radio wave reaching from a predetermined transmission point in a limited evaluation area to a plurality of reception points in the evaluation area and to estimate a component other than diffracted wave among the radio wave component reaching from the transmission point to the reception points; diffracted wave estimation device configured to estimate only a diffracted wave component among the radio components reaching from the transmission point to the respective reception points; and total radio wave component calculation device configured to calculate total radio wave propagation characteristics in the respective reception points considering the estimated result in the non-diffracted wave estimation device and the estimation result of the diffracted wave estimation device.
