System and method for heart rate detection with motion artifact reduction

Example embodiments relate to systems and methods for heart rate detection with motion artifact reduction. One embodiment includes an electronic system for heart rate detection. The electronic system includes a random sampling sensor module. The random sampling sensor module includes a first sensor circuit configured to provide nonuniform random samples below a Nyquist rate of a photoplethysmographic signal. The random sample sensor module also includes a second sensor circuit configured to provided nonuniform random samples below a Nyquist rate of a motion signal. The motion signal and the photoplethysmographic signals are sampled with an equivalent pattern. The electronic system also includes a heart rate detection module. The heart rate detection module is configured to calculate a heart rave value based on frequencies corresponding to peak powers of calculated power spectral density value sets corresponding to the photoplethysmographic signals in a frequency range of interest.
