Abstract:	The performance of Global Navigation Satellite Systems (GNSS) can be improved in certain environments (e.g. indoor or urban scenarios) by using additional comple- mentary systems, such as the use of wireless communica- tions signals. Indeed, multicarrier wireless systems provide many advantages for the integration of both communica- tions and positioning capabilities, such as the Long Term Evolution (LTE) that includes specific signals for position- ing, i.e. the positioning reference signal (PRS). The assess- ment of the LTE positioning signals is not straightforward in realistic scenarios. Thus, a methodology is proposed for the theoretical analysis of the typical LTE position errors, by considering the joint impact of interferences and mul- tipath. Preliminary results in an LTE coordinated network are shown using pedestrian and urban channel models.
