Schematic diagram of the proposed method. Initially, the raw data is extracted into epochs based on the QRS peaks. The K-SVD algorithm is used to learn a dictionary of atoms which are then used to represent the raw data epoch using OMP. The approximation is then subtracted from the raw LFP data, and the residual (denoised signal) was visualized.
