Separation of Aortic and Pulmonary Components from Second Heart Sounds without an Assumption of Statistical Independence

A novel algorithm to separate aortic (A2) and pulmonary (P2) components from the second heart sound (S2) without assuming that A2 and P2 are statistically independent, and with optimizing demixing vectors using root-mean-square error (RMSE) between outputs and signal models as cost function is succe...
