针对接收信号强度指示(RSSI)测距定位精度和鲁棒性差的问题,提出了一种基于秩滤波和裴波那契树的信号强度定位(RF-RSSI-FTO)算法.采用秩滤波方法对RSSI值进行去干扰滤波处理,可提高测距精度及鲁棒性;引入裴波那契树优化算法对定位坐标进行全局和局部搜索寻优处理,可减小定位误差.仿真结果表明,RF-RSSI-FTO算法能有效改善测距精度和鲁棒性,增强全局和局部搜索能力,提高定位精度.

In order to solve the problem of poor ranging accuracy and robustness of received signal strength indication (RSSI), a signal strength localization algorithm based on rank filter and Fibonacci tree optimization (RF-RSSI-FTO) was proposed. First, the rank filtering method was used to remove the interference of the RSSI value to improve the accuracy and robustness of the ranging. Then, the Fibonacci tree optimization algorithm was introduced to optimize the global and local search of the positioning coordinates to reduce the positioning error. Si...
