| Abstract: | A method which eliminates power line interference in the ECG based on QRD-LS algorithm is studied.QLD-LS algorithm which is recursive least-squares minimization using systolic arrays is employed in order to adjust the weight vector.Compared with LMS algorithm,it has good robustness.Because of adopting adaptive notch filter,it can automatically remove the power line interference in the ECG,and can also improve the signal-to-interference ratio.Simulated examples confirm the results. |
