Accurate position estimation using intensity-modulated optical signals

在许多情况下，关于人或设备的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，仍然没有适合于许多重要的室内应用的定位系统。用于室内照明的节能白色发光二极管（LED）的广泛引入提供了前所未有的机会，通过使用这些LED来发送接收器可以根据其计算其位置的信号来解决该问题。然而，使用调制光信号的位置估计的设计和分析的理论基础并不存在。该项目旨在发展这一基本理论基础，并将其应用于创建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.
