- W2937842630 abstract "Direct localization systems with large-scale antenna-arrays can greatly improve the localization accuracy by jointly processing all the observed signals. However, it incurs high communication overhead due to high-dimensional array signal transmission. In this paper, we propose a robust beamspace design technique in the presence of parameter uncertainty that can achieve high-accuracy positioning only with limited communication overhead. The beamspace design problem is formulated as a robust optimization in order to guarantee the worst-case performance in terms of the squared position error bound (SPEB). Since the problem is non-convex, we relax it to a convex programming and further prove that the solution of the relaxed problem converges to the optimal solution of the original problem. Simulation results validate the effectiveness and robustness of the proposed beamspace." @default.
