相比于其他定位系统通常至少需要3个参考基站的开销来说，UWB单基站定位只需要一个基站，系统配置简单，可以很快的被应用和发展。为了提高UWB单基站定位系统中对于距离的测定精度，提出了一种应用于该系统的通信定位协议。该定位通信协议用于更加精确地进行基站与标签之间的时钟同步。同时将最大概率数据处理方法应用于距离数据处理。通过对UWB单基站定位系统的整体仿真得到的距离测量误差小于5 cm。该仿真结果说明了此种定位协议和最大概率数据处理方法可以应用于室内高精度无线定位。

Compared to other positioning systems which requires at least 3 reference stations,Ultra-Wideband(UWB)sin-gle base station positioning only need one base station,and the system configuration is very simple,so it can be applied and de-veloped. In order to improve the distance measurement accuracy of UWB single base station positioning system,a communica-tion positioning protocol is proposed,which is used for more accurate clock synchronization between the base station and label. At the same time,the maximum probability data processing method is applied to distance data processing. Through the whole simulation of UWB single base station positioning system,distance measurement error can be reduced to less than 5cm. The simulation result shows the positioning data processing method and positioning communication protocol can be used in the preci-sion indoor wireless positioning.
