一种奇异信号测量中的小波分析方法 |
|
| [摘要] |
| 本文提出了一种新的信号奇异性检测方法——小波变换，理论与仿真结果证明，对于突变信号或孤立奇异性信号的处理，基于小波变换的奇异性检测方法其分辨率要高于FFT方法。文中详细讨论了小波的奇异什枪测算法，并给出了正弦奇异信号的仿真结果。 |

| In this paper,a new singularity detection method with wavelet transformation is given. It's also proved by theoretical and emulation that for transient signals or irregular structures, singularity detection based on wavelet transformation has better distinguishing rate than that of FFT. It also discussed the algorithm of singularity detection, and the singularity of sine emulating result is given at last. |
