文摘对于室内可见光定位,非视距(NLOS)信道的能量会明显干扰接收信号强度(RSS)算法的精度.为了提高NLOS情况下的可见光定位性能,研究了NLOS传输散射功率对二维室内定位的影响.针对视距(LOS)与NLOS功率强度总和情况,提出一种接收功率强度组合与距离加权因子(ICDWF)相结合的室内定位算法.该算法将接收的功率通过数值的大小进行分组,通过RSS算法分别算出各组的估计坐标.然后引入一种以距离放大系数为基础的权重系数,最后将权重系数引入各组的坐标来得到最终的估计坐标.仿真结果表明:在所搭建的5 m×5 m×3 m室内环境中,该方案与传统RSS算法相比,在室内NLOS能量较高的区域平均误差降低了0.23 m.
