摘要

试图确定不同的物理参数如何影响斜坡的大小和在视线(LOS)和非视线(NLOS)中损失的断点位置。提出了一种基于分段指数函数的NLOS传播模型。以计算损失和测量损失的平方误差为最小函数进行多参数回归，使测量数据与模型参数之间的拟合达到最佳。

Outdoor microcell measurements at 1700 MHz

An attempt is made to determine how different physical parameters affect the magnitude of the slopes and the location of the breakpoint for loss in both line-of-sight (LOS) and in non-line-of-sight (NLOS). A model for NLOS propagation using piecewise exponential functions is also presented. Multiparameter regression with the squared error between calculated and measured loss as minimizing function is performed to give the optimum fit between measured data and model parameters.<>
