摘　　要：为了解决无线网络规划中传播预测的准确性问题,并提高双斜率传播模型的实用性,该文提出了一种基于最小二乘法的迭代式双斜率传播模型校正算法,通过实验和仿真证明了算法的有效性,并给出了与单斜率传播模型的校正效果的对比,证明了双斜率传播模型的校正效果优于单斜率传播模型,更适合在无线网络规划中使用。A calibration algorithm of two-slope propagation model based on the recursive LLSM is expatiated in this paper to improve the accuracy of the propagation loss prediction in wireless network planning, and to improve the practicability of the two-slope propagation model. A comparison between the results of the calibrations of two-slope propagation model and single-slope propagation model is also presented, which proves the better performance of the former.
