An enhanced adaptive algorithm for PLI cancellation in ECG signals
- 1 December 2009
Abstract
This paper presents a technique for determining amplitude and phase of the power line interference (PLI), which is in sinusoidal waveform, by using two consecutive samples under identified sampling rate. The amplitude and phase information will then be employed to initialize parameters of the adaptive noise canceling algorithm whose the interfering noise is modeled as orthogonal sinusoidal functions. Based on computer simulation, the performance of the adaptive algorithm is improved over the conventional algorithm. In addition, the results in various cases of the PLI show that the proposed technique is superior to the results of the ASIC algorithm.Keywords
