| 摘 要： | 由于受到许多复杂因素影响,沉降监测过程中所得到的信号数据可能会含有噪声。Matlab中小波分析功能能够对信号数据中的噪声信号进行有效的分解,最后重构处理后的信号。通过实例对比,选用合适的去噪方法和去噪函数,对信号数据进行处理,最后能够得到更适合的最优估计。

The Application of Denosing in Wavelet Analysis in the Deformation Monitoring of Waist Sand Reclamation |

| Abstract: | Due to the impact of various complex factors,the signal data obtained during the process of subsidence monitoring may con-tain noise.The function of wavelet analysis in Matlab can effectively decompose the noise in signal data, and then reconstruct the pro-cessed signal.The case comparison shows that processing signal data via appropriate denoising method and denoising function can fi-nally achieve a more appropriate optimal estimation. |
