A Tractable Analysis of the Improvement in Unique Localizability Through Collaboration [article]

Javier Schloemann and Harpreet S. Dhillon and R. Michael Buehrer
2015 arXiv   pre-print
This occurrence is well-known to be a limiting factor in localization performance, especially in communications systems.  ...  In cellular positioning, for example, cellular network designers call this the hearability problem.  ...  In the absence of shadowing and all other things being equal, the results show that collaboration is more beneficial to range-based than range-difference-based positioning systems.  ...

Improving positioning in LTE through collaboration

Reza Monir Vaghefi, R. Michael Buehrer
2014 2014 11th Workshop on Positioning, Navigation and Communication (WPNC)  
Many applications, such as location-based services and Enhanced 911 (E911), require that the locations of users in a cellular system are available.  ...  In cellular localization, the locations of users are determined via measurements obtained within the network without aid of any external sources (e.g., GNSS).  ...  CONCLUSION In this paper, cooperative positioning in LTE systems was studied. Current cellular systems employ only noncooperative positioning methods.  ...
