提出了一种将可见光通信（VLC）与室内三维定位相结合的新概念。一个VLC链路的发射机和接收机的特性，使用实验测量的基础上建模。提出了一种利用接收信号强度指示的三维定位算法，该指示根据位置服务的角度和距离而变化。为了减少小区间干扰，发射机的位置码使用不同的子载波发送。实验结果表明，该算法可以准确地获取用户的位置（包括高度），并且不会产生小区间干扰。
A novel concept for integrating visible light communications (VLC) with three-dimensional indoor positioning is presented. A VLC link based on transmitter and receiver characteristics using experimental measurements was modelled. Proposed is a three-dimensional positioning algorithm using received signal strength indication, which changes based on the angle and distance of the location based service. To reduce inter-cell interference, the transmitter's location code was sent using different subcarriers. A demonstration shows that the proposed algorithm can obtain a user's position, including height, accurately and without inter-cell interference.
