Power interference removal algorithm based on kernel method
基于核方法的工频干扰消除算法

This paper proposed a novel power interference removal algorithm based on kernel method. The algorithm transformed power interference removal problem into blind signal separation problem using the method of constructing objective signals. It could conquer the nonlinear aberrance coming from signal collection sensors by data mapping using kernel method. It could get the useful signal without power interference removal using the temporal predictability for signal separation. Simulation results show that the proposed algorithm can conquer the nonlinear aberrance of sensor and remove the power interference in seism signal and electrocardiogram signal efficiently.
