Abstract: This work explores the feasibility of using inverted PPG signals to detect heart rate in window-sampling environments. Thresholding is applied to the signal and its derivative to initially ...

Abstract: This article presents, a mutual coupling reduction technique between a very closely spaced (1.8 mm) two-element microstrip-based multiple-input multiple-output (MIMO) antennas using a ...
