Visible light positioning (VLP) is a promising indoor localization system in which light emitting diode (LED) luminaires are used as positioning beacons. Data communication is an essential aspect of any VLP system, as each luminaire must transmit information about its own location to the receiver. The quadrature angular diversity aperture (QADA) is a new receiver designed specifically for VLP systems using angle-of-arrival estimation. Previous QADA research has focused only on positioning and assumed error-free communication. In this paper, we investigate, via simulations and experiment, the actual communication characteristics of a VLP system that uses a QADA receiver. We calculate the signal-to-noise ratio and bit-error-rates for a range of scenarios and demonstrate the impact of the dimensions of the receiver. We show that reliable communication is assured in typical operating scenarios, proving that communication will not be a limiting factor when using QADA in VLP systems.

使用正交角分集孔径（QADA）接收器的可见光定位（VLP）系统的通信方面。

可见光定位（VLP）是一种很有前途的室内定位系统，其中发光二极管（LED）灯具用作定位信标。数据通信是任何VLP系统的重要方面，因为每个照明器都必须将有关其自身位置的信息传输到接收器。正交角分集孔径（QADA）是专门为使用到达角估计的VLP系统设计的新型接收器。先前的QADA研究仅专注于定位和假定无错误的通信。在本文中，我们通过仿真和实验研究了使用QADA接收器的VLP系统的实际通信特性。我们计算了一系列场景的信噪比和误码率，并演示了接收器尺寸的影响。
