| 摘 要： | 提出了一种基于小波包算法重构离子电流信号的新方法,利用小波包分解对离子电流进行多分辨率分析,获得尺度能量分布特征信号.然后,进行小波包重构,再经过平滑滤波,恢复通道离子电流信号.仿真实验结果表明,采用小波包算法,在较低信噪比时,离子电流恢复精度高,算法收敛速度快,且具有较强的抗噪能力.

| Abstract: | A new approach based on wavelet package algorithm is introduced to reconstruct ionic current.The scale-power distribution of the signal is obtained by the multi-resolution analysis to ionic current using the wavelet package decomposing,and the signals are reconstructed by wavelet package reconstructing algorithm.After smooth filtering,the ideal ionic current is restored from Markov sequences contaminated by noise.The experimental results shows that this method can precisely reconstruct the ionic current und... |
