B on Localization and Positioning within the NEWCOM++ NoE. These results address a wide range of cutting-edge topics starting from measurements, channel modeling, parameter estimation, cognitive and cooperative positioning techniques, and arriving to Bayesian methods for data fusion and integration of hybrid positioning systems (eg, GNSS/terrestrial, radio/inertial ...

In addition, a node transmission strategy for the selection of the most profitable link is developed. The resulting strategies are fully distributed and do not rely on any explicit information exchange among network nodes.

When designing practical positioning techniques the main focus is on reducing the gap between theoretical and real performance and keeping the complexity of the estimator at reasonable level. This report presents the results related to position estimation techniques obtained in the first eighteen months of activity of NEWCOM++ WPR. B. Most of the material represents the outcome of joint activities ...

In particular, resorting to game theory, a novel strategy able to manage node participation in a distributed cooperative link using a simple randomized coding rule is derived. The proposed solution guarantees the participation of a proper number of nodes to a virtual antenna array (hence avoiding an energy waste) without requiring any overhead for node management.
