【 摘 要 】

In a world of advanced technology and its close integration within indoor environments, the ability to navigate people and devices indoors has become increasingly important for numerous applications. Global Positioning System (GPS) has solved the issue of positioning and navigation for outdoor environments. However, it fails to achieve a good indoor performance due to the lack of line of sight with the GPS satellites as well as drastic signal attenuation due to buildings. This calls for a new technology to address this field, thus making indoor positioning a focus of research and development in the past decade. This thesis discusses a positioning system called MERLIN, which is based on the phase information of CW RF signals. Different range estimation methods are also discussed. Indoor positioning or localization is bound to become a popular feature in the next generation of wireless systems.
