Present day wireless communication systems require a high data rate wireless access, for which the prerequisite is larger bandwidth. Obviously, to mitigate the inter symbol interference (ISI) caused by the multipath fading of high data rate communication system is orthogonal frequency division multiplexing (OFDM). The major challenging task in multiple input multiple output (MIMO) OFDM systems is...
Arterial blood oxygen saturation (SpO2) is effectively measured by the pulse oximeter. The common cause of pulse oximeter failure, in error- free SpO2 estimation, is motion artifact (MA) corruption in the detected PPG signals. For a reliable and a low failure rate SpO2 estimation, the pulse oximeters must be provided with a clean artifact-free PPG signals with clearly separable DC and AC parts from...
A pulse oximeter measures the arterial blood oxygen saturation (SpO2). The common cause of oximeter failure in computing error- free SpO2 is motion artifact (MA) corruption in the detected PPG signals. In order to have a low failure rate, the pulse oximeters must be provided with a clean artifact-free PPG signals with clearly separable DC and AC parts from which the SpO2 is computed in time domain...
The electrocardiogram (ECG) is an electrical manifestation of contractile activity of the heart. The presence of parasite interference signals, like power line interference (PLI), Electromyogram (EMG) or myopotential signals and baseline drift interferences, could cause serious problems in the registration of ECG signals. Many a time, they pose problem in modern control and signal processing applications...
Photoplethysmographic (PPG) signals obtained at Red and Infrared wavelengths are utilized in pulse oximetry for estimation of arterial blood oxygen saturation (SpO2). Mostly inaccurate readings in a pulse oximeter arise when PPG signals are contaminated with motion artifacts (MA) due to the movement of patient and hence MA are a common cause of oximeter failure and loss of accuracy. This paper presents...
