论文摘要
在这个通信革命时代，可见光通信（VLC）是对增加高速数据传输请求的最佳有效答案，除了照明之外，成本降低。由于其具有更高的位置准确性的能力，与其他技术相比，这项技术被认为是室内定位的最佳有前途的候选人。但是，基于VLC的室内定位系统（IPS）应用的现有技术的重点是精确度，但忽略了成本和复杂性的各个方面。本文提出了一种基于接收的信号强度（CSA-RSS）的定位新技术，即互补和补充角度。根据单个发光二极管（LED）和光电二极管（PD）的不同位置检查系统的定位误差性能。结果表明，提高的精度并证明了新提出的技术的有效性，在80％的位置中，平均误差为3.2 cm，最大平均定位误差为4.2 cm。此外，已被证明该方法可以提高系统效率，该效率是适合室内定位性能的合适VLC设计，避免了信号较弱
In this communication revolution era, visible light communication (VLC) is the optimum efficacious answer to the increased request for high-speed data transmission with reduced cost, besides the illumination. This technology is considered the best promising candidate for indoor positioning due to its ability to attain higher positioning accuracy than other technologies, alongside its distinct advantages. However, the existing techniques that had been applied in an indoor positioning system (IPS) based on VLC focused on the aspect of accuracy but neglected the aspects of cost and complexity. This paper proposes a new technique for positioning, namely complementary and supplementary angles based on received signal strength (CSA-RSS). The positioning error performance of the system is examined based on the single light-emitting diode (LED) and different positions of the photodiode (PD). The results demonstrate the improved accuracy and prove the effectiveness of the newly proposed technique where the average error is 3.2 cm in 80% of the examined positions and the maximum average positioning error is 4.2 cm. Moreover, the proposed approach has been proven to increase system efficiency which acts as a suitable VLC design for indoor positioning performance, avoiding weak signals
