[description]
Ultra Wide Band (UWB) technology is a wireless carrier communication technology. It does not use a sine carrier, but uses nanosecond non-sine wave narrow pulses to transmit data, so it occupies a very wide spectrum. The accuracy of UWB is an important indicator of UWB performance. In terms of UWB accuracy improvement, there are currently two directions, one is the data correction problem for the UWB chip DW1000, and the other is the UWB label positioning algorithm problem. The most commonly used UWB label positioning algorithms by global manufacturers are the trilateral positioning algorithm and the centroid positioning algorithm. The data correction method of the most DW1000 is the linear regression equation. This project is based on trilateral positioning and uses data fusion to expand a new type of trilateral positioning and error optimization algorithm. And optimize and upgrade the data transmitted by DW1000, refine the linear interval, and make it develop into a nonlinear equation.
