Requirements for 5G based telemetric cardiac monitoring

“…Network bandwidth requirements are not only dependant on the original signal size, but also on potential security features, such as encryption, meta data and most famously on the noise level of the communication channel [11]. This typically translates into uplink baud rates of around 3.6 -20 kbps per patient [12,13].…”

Time-varying FIR notch filter implementation using Raspberry Pi

“…According to [14], [15], a good way to evaluate the performance of the proposed approach for the reduction of the transient response is to calculate the SNR Improvement (SNRimp), the cross-correlation coefficient (ρ), the percentage root mean square difference (PRD), and the mean squared error (MSE). 1) SNR improvement…”

A Low-Complexity Model-Free Approach for Real-Time Cardiac Anomaly Detection Based on Singular Spectrum Analysis and Nonparametric Control Charts

“…The ubiquity of powerful smartphones and other smart devices, which nowadays incorporate a plethora of advanced sensing capabilities, has led to an increasing trend in the consumer sphere to continuously gather and evaluate physiological signals [1,2]. In particular, cardiovascular parameters such as heart rate (HR) and pulse rate (PR), extracted respectively from measurements of myocardial electrical potentials through electrocardiographic (ECG) observations [3][4][5][6] and from measurements of volumetric changes in blood perfusion during cardiac cycles by optical means through photoplethysmographic (PPG) observations [7][8][9], are being recorded and analyzed in apps, fitness trackers and so forth, with great potential benefits for public health [1,[10][11][12].…”
