Power Line Interference Removal Method Based on Unifying Model Blind Separation Algorithm

Abstract:

A novel power line interference removal method based on blind signal separation algorithm was proposed. The regular methods for power line interference removal were notch filter method and adaptive filter method. Part of the frequency component in desired signal would lose if there was same frequency component between power line interference signal and desired signal. The desired signal and the power line interference signal was commonly coming from different source. The power line interference removal problem was transformed into blind signal separation problem by constructing observation signal artificially. The blind separation algorithm based on unifying model was used for solving the transformed blind separation problem and the desired signal without power line interference could be got. The simulation results on electrocardiogram signal show that the power line interference can be removed efficiently using the method proposed and the signal recovery precise is high.
