Pairwise Distance and Position Estimators From Differences in UWB Channels to Observers
Gregor Dumphart, Robin Kramer, Armin Wittneben
We consider the problem of obtaining relative location information between two wireless nodes from the differences in their ultra-wideband (UWB) channels to observer nodes. Our app…
Pairwise Node Localization From Differences in Their UWB Channels to Observer Nodes
Gregor Dumphart, Robin Kramer, Robert Heyn +2
We consider the problem of localization and distance estimation between a pair of wireless nodes in a multipath propagation environment, but not the usual way of processing a chann…
Cooperative Magneto-Inductive Localization
Henry Schulten, Gregor Dumphart, Antonios Koskinas +1
Wireless localization is a key requirement for many applications. It concerns position estimation of mobile nodes (agents) relative to fixed nodes (anchors) from wireless channel m…
Practical Accuracy Limits of Radiation-Aware Magneto-Inductive 3D Localization
Gregor Dumphart, Henry Schulten, Bharat Bhatia +2
The key motivation for the low-frequency magnetic localization approach is that magnetic near-fields are well predictable by a free-space model, which should enable accurate locali…
Inter-Node Distance Estimation from Multipath Delay Differences of Channels to Observer Nodes
Gregor Dumphart, Marc Kuhn, Armin Wittneben +1
We study the estimation of distance d between two wireless nodes by means of their wideband channels to a third node, called observer. The motivating principle is that the channel…
Magneto-Inductive Powering and Uplink of In-Body Microsensors: Feasibility and High-Density Effects
Gregor Dumphart, Bertold Ian Bitachon, Armin Wittneben
This paper studies magnetic induction for wireless powering and the data uplink of microsensors, in particular for future medical in-body applications. We consider an external mass…
