摘要: 讨论适合于TDOA定位的信道模型,分析1种典型TDOA定位算法———Taylor级数展开法,并针对其收 敛问题提出改进方法。结合不同信道环境和蜂窝基站位置分布,对Taylor级数展开法的性能进行仿真,并就各 种环境参数对算法性能的影响,与其它算法进行分析比较。Abstract: The channel model suitable for TDOA techniques is discussed, and the typical location TDOA algorithm, Taylor series expansion method, is analyzed. The traditional Taylor series expansion method is improved by solving its convergence problem. Then, the performances of the improved method are simulated under different channel environments and cellar base station distributions. And, a comparison is made between the improved Taylor series expansion method and the other methods in influences of various parameters on the performances.
