Abstract
A position estimating device () which estimates the position of an object by comparing a receiving pattern obtained from ID transmitters (, . . . ) and ID receivers (, . . . ) installed in an environment with a prestored receiving pattern. Position of an object equipped with no extra device can be estimated only with the ID transmitters and ID receivers installed in an environment even in an indoor multipath environment by utilizing a fact that a receiving pattern obtained from ID transmitters (, . . . ) and ID receivers (, . . . ) installed in an environment changes depending on the position of the object.
