基于奇异值正交分解ECG信号的重建

The Reconstruction of ECG on SVD

ECG经奇异值正交分解后 ,将信号分解到信号空间和噪声空间中。利用分解后的信号空间来进行信号的重建 ,以达到消噪的目的。利用重建后的信号 ,对 ECG中的 ST波段和

The electrocardiogram(ECG) is decomposed on the single value decomposition(SVD) into two time-orthogonal subspaces, one containing ECG and the other containing artifacts, the subspace containing ECG is used to reconstruct the signal to eliminate the artifacts. The ST-segment is detected and analysized.
