| 摘 要： | 本文给出一个种改进的信号多尺度估计算法，即对多尺度分解出的细节信号再继续作小波变换，对分解后得到的次平滑信号的次细节信号分别作不同程度的阈值处理，对阈值处理后的信号进行重构，作为相应尺度上的细节信号，对最粗尺度上的平滑信号进行卡尔曼滤波，再次与各尺度上细菌信号进行重构，最后得到原始尺度的信号估计值。

| Abstract: | In this paper an improved multi_scale estimation method of signal is gaven.The detail signals on each scale are further more decomposed with wavelet transform.The subdetail signals and subsmoothing signals are processed with different threshold respectively. The smoothing signals on the coarsest scale are processed with Kalman fitering and reconstructed with the detail signal on each scale.At last the signal estimate value on the original scale is obtained. |
