چکیده مقاله :
با استفاده از روشي که در اين مقاله ارائه ميگردد، امکان حذف و کاهش نوفه از سيگنال ECG در شرايط کاري سخت و پرنوفه فراهم ميگردد. در اين مقاله با استفاده از الگوريتم بهبود يافته LMS بصورت گامهاي متغير (MVSS) نتايج بهتري نسبت به روش تطبيقي معمولي بدست ميآيد
We present a new adaptive noise cancellation method for ECG noise cancelling in very difficult conditions. This method is based on modified variable step size LMS algorithm. We show that the proposed algorithm is more efficient and the adaption speed is higher than conventional LMS
