This paper introduces the use of chaotic Duffing oscillators to ballistocardiograph system for detection of weak signal. A ballistocardiograph (BCG) is an instrument that records the motions of the body imparted to it by the heart beat. It has been found that digital filters are not suitable for processing the BCG signals in noise. So in this paper, we propose a chaotic oscillators algorithm to detect...
Ballistocardiogram (BCG) is a new, noninvasive technique used to record the movement of the body synchronous with the heartbeat due to left ventricular pump activity. However, BCG signal is so weak and easy to be jammed. In this paper, we achieved it through the measure system which is made by our BCG laboratory. Then, attempt to detect useful information from noises by chaotic oscillators. Experimental...
