Abstract: Highlights•Low-complexity PPG signal recovery algorithm for real-time health monitoring.•ANFA to remove in-band and out-of-band motion artefact at various physical activities.•Accurate HR and RR values obtained from four stages of two exercise protocols with 24 subjects.•Smaller absolute error in HR and RR values using ANFA, than using published methods.
