2D indoor mapping and location-sensing using an impulse radio network

This paper describes a location-sensing technique suitable for impulse radio ad-hoc networks operating indoors. This technique has similarities to hyperbolic navigation and bistatic radar, but it does not use any fixed references. Given the channel impulse responses (CIRs) of transmitter/receiver pairs communicated around the network, we show that this technique can successfully map typical indoor environments comprising two and four walls in relation to communicating radios. The technique can be extended to solve more complex scenarios.
