Research on UWB Indoor Positioning Based on TDOA Technique

摘要：

Ultra wideband (UWB) wireless communication technology has been regarded as a very important way of indoor short distance,high speed transition at present.In this paper the system structures and working principles of indoor positioning using UWB are introduced. The basic location principles and realization ways based on TDOA (Time Dijference-of Arrival) are discussed and a new method to estimate the value of TDOA is proposed.In the indoor positioning system,the content being transmitted are simple,the system complexity is low,and it is prone to link with other outdoor positioning system such as GPS to realize accurate positioning.
