Summary:
In this paper, we therefore discuss the possibility to break the locality, i.e., to estimate the received signal at a distant location in a multipath fading environment. We attempt to estimate the received signal characteristics based on the observed signals at multiple different points at a certain distance from the target. The principle of the estimation technique is firstly introduced and the estimation performance of the technique is then evaluated quantitatively via computer simulations. Also the performance when the estimation parameters such as the distance between the observed and the estimated points are varied is analyzed. The mechanism of the estimation methods is clarified through the analysis assuming a simpler propagation model. In order to clarify the estimation performance in more practical environments, we also consider a noisy channel model. From the results of the analysis we conclude it is difficult to precisely estimate the received signal from remote multiple observation points.
