文章文针对基于TDOA的Taylor级数展开法在蜂窝网移动通信定位过程中初始值不易选择的问题,提出了一种基于最小二乘法和Taylor级数展开法的协同定位算法,将最小二乘法的定位结果作为Taylor级数展开法的初始值,仿真结果表明,该法的定位精度要高于最小二乘法和Taylor级数展开法。 Article In order to solve the problem that the initial value of Taylor series expansion method based on TDOA is not easy to choose in the cellular mobile communication positioning process, a coordinated positioning algorithm based on least square method and Taylor series expansion method is proposed. The least square method Positioning results as the initial value of the Taylor series expansion method, the simulation results show that the positioning accuracy of the method is higher than the least square method and the Taylor series expansion method.
