Decoupling Estimators in Mobile Cooperative Positioning for Heterogeneous Networks

Positioning in wireless communications represents nowadays an important topic in the research community. The main reason is the increasing number of new location based services available on the market. Since some types of these services require accurate positioning information, research has evolved in the direction of overcoming the adverse propagation effects that commonly degrade accuracy of positioning solutions. One approach to overcome propagation effects is to consider cooperative schemes where close-by users share information regarding their links. However, due to the coexistence of numerous technologies, heterogeneity and interaction between technologies shall be regarded as an additional problem. This paper proposes and analyzes a positioning framework for cooperative schemes, which is specifically beneficial for scenarios with heterogeneous link technologies.
