Location Accuracy of Radio Emission Sources for Beamforming in Ultra-Dense Radio Networks

Current trends in ultra-dense radio networks include wide utilization of beamforming techniques. Successful implementation of simultaneous transmission and reception is possible by means of preliminary location of neighboring stations. Contribution of the current research is location accuracy limits estimation for positioning of radio emission sources using time difference of arrival in 3D with sensors aboard UAV. Resulting accuracy limits, such as Cramer-Rao lower bound ellipsoid and spherical error probability contour were analyzed and visualized to confirm spatial splitting possibility of neighboring RES in dedicated short-range communications for 200 m separation in dense-urban scenario.
