Transmission path estimation method

Uses transmission route forming method according to the present invention the estimation method is to use a transmission path imaging methods estimation method having the following steps: there is a reflection on the transmission path (RX) up from the transmission point of the radio wave (TX) to a receiving point downward direction and scattering direction [theta] with the direction of specular reflection ° different directions (θ-η) ° construct the circumstances, the rotation center point (O) as a center point of the receiving (RX) [eta] ° rotation, thereby calculating virtual reception point (VRX), using the virtual reception point (VRX) to estimate the propagation path.
