Using the continuous-wave (CW) Doppler radar to identify and extract the respiratory rates of two subjects is challenging, especially when the subjects have time-varying respiratory rates. In this work, a novel wavelet-transform-based algorithm is proposed to obtain the respiratory rates for the sce...
