Abstract

Abstract : An indoor optical wireless positioning system using a differential of power received by tilted multiple optical receivers is proposed. The proposed system is based on gain difference by angle of arrival with a fixed single optical transmitter that is a white light‐emitting diode. A demonstration shows that the proposed structure and algorithm estimates position successfully without requiring the characteristic information of the transmitter.
