Separation of the Aortic and Pulmonary Components of the Second Heart Sound via Alternating Optimization

IEEE Access
An algorithm for blind source separation (BSS) of the second heart sound (S2) into aortic and pulmonary components is proposed. It recovers aortic (A2) and pulmonary (P2) waveforms, as well as their relative delays, by solving an alternating optimization
