A good night's sleep is an important part of a healthy life. Sleep can affect quality of life as
much as eating and exercise do. Unfortunately, the accelerated pace and pressure of life …

In this paper, a noncontact breathing disorder recognition system has been proposed for
identifying irregular breathing patterns. The proposed system consists of a Doppler radar …

The instantaneous vital sign rates, which are related to physiological dynamics, are
important indicators of human health condition. This paper presents a noncontact way to …

The challenge of noncontact presentation of human cardiopulmonary activity using a
bioradar sensor is to linearly demodulate the Doppler cardiopulmonary diagram (DCD) …

The quadrature continuous-wave (QCW) radar has been extensively studied for small
vibrational displacement detection such as non-contact sensing of human vital signals. One …

Time-varying vocal folds vibration information is of crucial importance in speech processing,
and the traditional devices to acquire speech signals are easily smeared by the high …

Noncontact techniques for detecting vital signs have attracted great interest due to the
benefits shown in medical monitoring and military applications. A rapid remote evaluation on …

This paper presents a novel design of human vital sign detecting microwave radar system
enlightened by a natural radar system. The system mimics the physical structure of microbat …

Language has been one of the most effective ways of human communication and
information exchange. To solve the problem of non-contact robust speech recognition …

Dc-offset estimation of quadrature continuous-wave (CW) radar has been studied for years.
Studies have shown that the estimation error increases when target movement with respect …
