Algorithm is to significantly remove muscle artifact, electrode motion noise and additive white Gaussian noise which usually exist in ECG signals. The singular value decomposition (SVD) has been already exploited to clean the ECG noisy signals, but the denoised signals usually suffer from residual noise due to the dispute in the strategies followed to determine signal and noise eigencomponents. The first stage is a regular SVD whose data output is divided into overlapped groups. Each group is then arranged in a Hankel matrix to expand the processing space. Thereafter, SVD is applied again on each Hankel matrix to track the rest of the noise which becomes evident by enlarging the processing space.
