Abstract

The availability of positional information is of great importance in many applications. Global Navigation Satellite System (GNSS) is the most popular positioning techniques. However, determination of devices’ positions is still a challenging task in harsh environments due to radio blockage. In this situation, cooperative positioning can be utilized to improve the ability to compute position. This paper derives the expression for Cramér-Rao lower bound (CRLB) in cooperative positioning, where parts of the propagation paths between devices are non-line-of-sight (NLOS). Numerical examples illustrate our results, and the results lead to a deep understanding of the benefits of cooperation.
