Angle-of-arrival (AOA) estimation of optical signals is a key technique in visible light positioning (VLP) systems, which can be realized using photodiode (PD) arrays. However, most of existing works do not properly design the angles of the Plls, which hampers the accuracy of VLP systems. In this work, we optimize the PD array to achieve the highest AOA estimation accuracy. Specifically, we achieve the optimal angle combination of the Plls in order to minimize the power of the additive Gaussian noise imposed on the exact incident vector. Closed-form expressions are derived for the optimal angles of the PD array. Our analytical results show that improper placement of Plls can cause significant accuracy loss. Both simulation and experimental results show that the optimized Pll array can suppress the angle estimation noise. The theoretical results provide a benchmark for the design of PD arrays, and lay a foundation for further studies on error analysis of VLP. |
