Spatially Resolved Multi-Transmitter Ka-Band Channel Measurements for Receiver Localization
Abstract
In this paper, spatially resolved simultaneous multi-Transmitter Ka-band channel measurements were realized. The measurements were performed at 28.5 GHz with a bandwidth of 2 GHz. The experiment's objective was to implement a receiver localization by using a correlative measurement setup and perfect uniform families within a measurement window. The receiver was localized by evaluating time of arrival and angle of arrival information without any a priori knowledge, except the transmitters' positions. An outdoor measurement campaign was carried out in a rural environment of which the executed scenarios differed in transmitter and receiver positions. For verification and comparison, a real time kinematic global positioning system reference was used. Based on the evaluation of collected measurement data, an average accuracy of 2.99 m and a maximum accuracy of 15 cm was achieved for the localization. Experimental results reported that the accuracy decreases for longer distances between transmitters and receiver due to decreasing signal-To-noise ratio and decreasing angle resolution.
