MATLAB数据字典生成代码逐块样条样条Wigner-Ville分布(PW-WVD)MATLAB软件包V1.0 [1] 提供此存储库中的材料以补充以下文章: M. Al-Sa'd,B。Boashash和M. Gabbouj,“用于TFD性能评估和比较的最优逐条样条Wigner-Ville分布的设计”, IEEE信号处理事务,2021年。 该存储库中列出的MATLAB脚本,函数和数据集用于产生结果,并提供本文中说明的支持图。 演示脚本: 开发的PW-WVD软件包在其主目录中包含以下演示脚本: Demo_1_example_simulation.m 描述:该演示脚本产生的结果在本文的图2中进行了描述。 处理:它生成示例2分量非平稳信号,并计算其PW-WVD,WVD和WVD交叉项。 此外,它还显示信号IA,IF和时间支持功能。 Demo_2_tfd_comparison.m 描述:该演示脚本产生的结果在本文的图3中进行了描述。 处理:它生成示例2分量非平稳信号,并使用chi原子计算理想的信号TFD,PW-WVD和MPD。 请注意,MPD是预先计算的,并保存在MPD_example.mat中。
