摘　　要：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。A new cooperative locating algorithm based on least square and Taylor series is presented. The outcome of the least square algorithm is used as the initial value of Taylor series in the cooperative locating algorithm, thus to over come the difficulty in choosing initial value when Taylor series algorithm is adopted during the cellular network radio positioning. The simulation results indicate that this algorithm has achieved better performance on positioning accuracy and efficiency than the least square and Taylor series algorithm.
