Design of Motion Artifacts Filter of PPG Signal based on Kalman filter and Adaptive filter

Design of Filter to Reject Motion Artifacts of PPG Signal by Using Two Photosensors

The photoplethysmography (PPG) signal measured from a mobile healthcare device contains various motion artifacts occurring from a patient’s movements. Recently, to reject the motion artifacts, the method of using an acceleration sensor was suggested, but such sensors are very expensive. Therefore, this study deals with a novel sensor device to replace the acceleration sensor, and evaluated the ...

Design of AS-LMS Adaptive filter for reduction of Motion Artifacts in PPG signals

This paper proposes a simple and efficient approach for reducing Motion Artifact (MA) in corrupted PPG (Photo Plethysmo Graphic) Signals based on AS-LMS Adaptive Filter. The performance of pulse oximeters is highly influenced by motion artifact in PPG signals. To generate the noise reference signal for an adaptive filtering process, instead of using any additional hardware such as accelerometer...

Doppler and bearing tracking using fuzzy adaptive unscented Kalman filter

The topic of Doppler and Bearing Tracking (DBT) problem is to achieve a target trajectory using the Doppler and Bearing measurements. The difficulty of DBT problem comes from the nonlinearity terms exposed in the measurement equations. Several techniques were studied to deal with this topic, such as the unscented Kalman filter. Nevertheless, the performance of the filter depends directly on the...
