LTE FDD传播模型校正

LTE FDD Propagation Model Calibration

通过对友谊路局等3个密集市区和设计院等3个一般市区的实际CW路测,并对测试数据进行过滤和筛选,采用迭代拟合及均方差最小的方法,校正2.1G LTE FDD的Cost-231-哈塔经验传播模型的C0和C1参数,得到适合规划区域的2.1G LTE FDD密集市区和一般市区的传播模型。通过校正后的传播模型,计算密集市区和一般市区的覆盖半径及站间距,以指导LTE网络建设。

By the actual CW drive test for three dense urban areas （such as Friendship Railway Administration） and three general areas （such as Design Institute） and filtering the test data, C0 and C1 in Cost-231-Hata propagation model of 2.1G LTE FDD are calibrated by using the iterative fitting and mean square deviation, and then a propagation model suitable for both dense urban areas and general areas of 2.1G LTE FDD is acquired. After the calibration for the propagation model, the coverage radii and station distance of dense urban areas and general areas are calculated to guide the LTE network construction.
