    Abstract

    In this paper, the transfer function of the upper arterial tree from heart to upper extremities is estimated via cross-relation based blind source identification. The photoplethysmogram from left and right arm index fingers were recorded at 275 Hz at 16 bits of resolution. The model order has been evaluated utilizing SVD decomposition of the ordered data matrix. After pre-processing the PPG signal, the AC signal is utilized to estimate the impulse response of the arteries from the heart to the left and right indices respectively. The proposed technique can be valuable in non-invasive vascular characterization of patients suffering from diseases affecting their arteries.
