A Bio Signal Processing System for Pulse Wave Velocity Detection
نویسندگان
چکیده
Pulse wave velocity (PWV) is the most popular index to assessment the arterial stiffness. Currently, several non-invasive examination methods with single channel for PWV are announced. This paper proposes a non-invasive digital volume pulse (DVP) measuring system using a dual channel simultaneous measurement method try to meet the demands for home healthcare equipment which is easy to operate. Through synchronal technical in measuring DVP signals from finger and toe can achieves more precise time and substantially reduces the time spend in measurement procedures. In addition, the proposed system assessed from dual-channel PPG is well correlated with the traditional method and can be used for evaluating cardiovascular risk factors. Index Terms Pulse wave velocity, arterial stiffness, photoplethysmography , digital volume pulse.

Vibration sensing by laser radar with a pulsed emission is a promising technique for long range target recognition and identification. However, compared to its continuous-wave counterpart, it is impaired by its greater sensitivity to speckle noise and its lack of robustness to multiple independent vibrations of the target surface. Using poly-pulse waveforms for greater velocity resolution, we d...
