PPG-based heart rate estimation using Wiener filter, phase vocoder and Viterbi decoding
ICASSP 2017accepted
Accurate heart rate (HR) estimation from the photoplethysmographic (PPG) signal during intensive physical exercises is tackled in this paper. Wiener filters are designed to attenuate the influence of motion artifacts. The phase vocoder is used to improve the initial Discrete Fourier transform (DFT)…
