| 摘 要： | 时域多分辨分析法（MRTD）是电磁场仿真计算的新方法,其核心是时频分析的小波函数问题。为提高MRTD方法的计算效率和精度,如何选择小波函数成为MRTD算法中有待解决的问题。本文简要给出了MRTD方法的推导过程。重点研究Haar、Coiflet、Daubechies小波基函数的紧支性、消失矩、光滑性特性对于MRTD方法的计算精度和效率的影响问题。最后通过对比基于Haar、Coiflet、Daubechies 3种小波基的MRTD方法对PCB电路板线间串扰的仿真结果,得到在相同精度下,选择小波基函数使得MRTD算法计算效率最高的方法。即,在精度要求比较高的情况下可选用计算效率相对较高的db4小波函数;反之,在精度要求不高的情况下,为提高计算效率,可选用Harr小波函数。 |
