摘　　要：为了提高路径损耗预测的准确性,提出一种快速且精确的传播模型校正方法。该方法基于最小二乘理论,在现有校正方法和本地连续波(CW)实测数据的基础上对本地标准宏蜂窝传播模型进行校正。仿真结果表明,该方法的计算复杂性明显减少,且校正后的模型最大预测错误率减少20.5%,与本地无线传播环境更加匹配。To improve the accuracy of path loss prediction, a fast and precise tuning method based on linear least-square theory is proposed in this paper. This method dependes on existed tuning methods and the Continuous Wave （CW） testing data of a certain city to tune the standard general macro cell propagation model. The simulating results indicate that the calculating complexity is reduced obviously, and the maximum error of forecasting data calculated by tuned model is reduced by 20.5%. The tuned model matches the local ratio propagation environment much better.
