三次样条插值在通信工程中的应用

在通信工程实践中,经常会遇到离散测量数据的拟合问题,即用已知的有限样本估计一些缺失的未知样本,这时就需要借助插值运算。通过对三次样条插值算法进行研究,将其应用至自由空间损耗计算、馈线插入损耗估计、相关干涉测向3个方面,并通过仿真验证三次样条插值算法在通信工程应用中的有效性。...

Summary:在通信工程实践中,经常会遇到离散测量数据的拟合问题,即用已知的有限样本估计一些缺失的未知样本,这时就需要借助插值运算。通过对三次样条插值算法进行研究,将其应用至自由空间损耗计算、馈线插入损耗估计、相关干涉测向3个方面,并通过仿真验证三次样条插值算法在通信工程应用中的有效性。
Bibliography:In the communication engineering practice, it often needs to estimate the unknown samples which are missing with the limited samples, then the interpolation operation is needed. Based on the research of cubic spline interpolation, the validity was given in communication engineering applications of the cubic spline interpolation by the experimental results on free space loss calculation, feeder insertion loss estimation, correlative interferometer.
