Application of UWB based Multi Base Station Efficient DS-TWR Ranging Algorithm in Intelligent Shopping Cart
This paper explains an efficient DS-TWR ranging algorithm based on UWB for multiple base stations.It reduces the number of ranging message frames through time-division control(TDMA)of ranging message frames,and automatically assigns ranging time points to each tag through time slot control of the base station,so that the tags work in an orderly manner.The experimental results show that this ranging method has the characteristics of low tag power consumption,large tag capacity,small ranging delay,and fast system response.
