Abstract: A positioning system and method includes a transmitter, a receiver, and a controller. The transmitter includes at least one energy source configured to emit an optical or quasi-optical electromagnetic signal as a channel communication. The receiver includes at least one detector element configured to receive the channel communication. The controller is connected to the receiver and configured to estimate a position of the transmitter within a space using a reference map of the space and one or more diffuse components of an impulse response of the channel communication.

Abstract: A method and system of indoor positioning associated with a smartphone includes installing one or more color LED identifiers on a ceiling associated with an indoor location and dividing the indoor location based on the one or more color LED identifiers into one or more cells. One or more images of the one or more color LED identifiers are captured through a camera associated with the smartphone. Further, accelerometer data associated with the smartphone is captured onto a memory associated with the smartphone. The accelerometer data and captured images are transmitted over a computer network to a computer processor and one or more of a location (two dimensional and/or three dimensional) in one or more cells, azimuth and tilt associated with the smartphone are calculated through closed form equations. The location of the smartphone is determined within the cell based on an identified cell of the one or more cells.
