Accurate position estimation using intensity-modulated optical signals

在许多情况下，关于人员或设备位置的准确信息是必不可少的。然而，尽管在世界范围内进行了广泛的研究，但仍然没有适合许多重要室内应用的定位系统。节能白光发光二极管（led）在室内照明领域的广泛应用为解决这一问题提供了一个前所未有的机会，通过使用这些led来传输信号，接收器可以计算其位置。然而，基于调制光信号的位置估计设计和分析的理论还不存在。本项目旨在发展这一基本理论基础，并将其应用于未来的精确室内定位系统。

Accurate information about the position of a person or device is essential in many situations. However, despite extensive worldwide research, there is still no positioning system suitable for many important indoor applications. The widespread introduction of energy efficient white light emitting diodes (LEDs) for indoor lighting provides an unprecedented opportunity to solve this problem by using these LEDs to transmit signals from which a receiver can calculate its position. However the theory underlying the design and analysis of position estimation using modulated optical signals does not exist. This project aims to develop this fundamental theoretical basis and apply it to create the accurate indoor positioning systems of the future.
