| 摘 要： | 本文提出一种抗NLOS干扰的TDOA定位算法。基于混沌优化算法对TDOA算法做了改进,采用混沌优化算法计算初值,再利用Taylor级数展开法进行定位。根据产生混沌序列的两种映射Logistic映射和Kent映射的特点,提出了Kent-Logistic模型修正Logistic映射用于定位。在移动台距服务基站较近时,直接采用该模型进行定位。通过和传统蜂窝定位算法的仿真结果进行比较,表明提出的算法能够提高NLOS传播环境下的定位精度。 |

| Abstract: | We propose an anti-NLOS algorithm for TDOA-based location. Chaos optimization algorithm (COA) can get the global optimization because of the ergodicity merit in chaos orbit. A novel chaos optimization is adopted for wireless location based on Taylor series expansion (COWLAT), firstly, we use the COA to get a optimization value, and then apply this value for the initial value of Taylor series expansion method. Considering the statistical property of chaotic sequence of Logistic Mapping and Kent Mapping, the ... |
