求翻譯:The process for wavelet de-noising and refactoring is as follows: first, take the ECG signal with noise into wavelet decomposition, choose wavelet basis and determine decomposition level for N. Usually noise is included in the high frequency part, and then to the high frequency coefficients of the wavelet decomposition是什么意思?![]() ![]() The process for wavelet de-noising and refactoring is as follows: first, take the ECG signal with noise into wavelet decomposition, choose wavelet basis and determine decomposition level for N.

小波去噪和重構(gòu)的過程如下:第一,考慮到小波分解噪聲的心電信號(hào),選擇小波基,并確定分解層次為N。噪聲通常是在高頻部分,然后向高閾值閾值量化的過程小波分解的高頻系數(shù),采取了一些“細(xì)節(jié)”,然后用于重建信號(hào)小波逆變器,這樣才能得到消除干擾信號(hào),達(dá)到消除噪音的目的。

這一進(jìn)程為wavelet抗擾和refactoring如下:第一,采取了心電圖信號(hào)與噪音納入wavelet分解,選擇wavelet基礎(chǔ)和確定分解一級(jí)為N.

過程為小波de吵鬧和refactoring是如下: 首先,采取ECG信號(hào)以噪聲入小波分解,選擇小波依據(jù)并且確定分解水平為N。 通常噪聲包括在高頻率部分,然后到小波分解的高頻率系數(shù)
