摘要:
针对电波传播损耗经验模型COST231-Hata模型在不同地区误差较大这个问题,提出基于Memetic算法对COST231-Hata的修正。将模型中两个参数作为变量,将实测值与预测值的最小均方误差和平均误差加权相加作为适应度函数,得出适用于本地的修正模型。数据显示,经过修正后模型误差明显减小,具有一定参考性。
Abstract:
Aiming at the problem that the empirical model of radio propagation loss cost231-hata has a large error in different regions, a modified cost231-hata based on Memetic algorithm is proposed.Two parameters in the model were taken as variables, and the minimum mean square error and average error weighted addition of the measured and predicted values were taken as fitness functions to obtain a local correction model.The data show that the model error is obviously reduced after correction, which has certain reference value.
