Tracking of multipath delays for UWB based positioning

In English

Författare

Summary, in English

Outdoor positioning systems are commonly available and typically rely on satellite navigation. The same is not true for indoor positioning systems. Severe multipath, non line-of sight to satellites and moving objects are some of the aspects that make the task of indoor positioning tricky. In this paper, we analyse different tracking methods to estimate and track the delay evolution of a radio channel multipath components for the case of a moving receiver and a fixed transmitter in a static indoor environment. UWB Channel measurements were performed and the different methods were used to track the delays of the multipath components. Those delays are then fed to a so-called structure from motion algorithm that computes the receiver motion. For several of the implemented methods, the final positioning errors are in the order of one cm.
