METHODS, SYSTEMS, AND DEVICES FOR BREATHING MONITORING

Abstract: embodiments of the present disclosure include methods, systems, and devices for breathing detection and monitoring comprising: receiving, via a data interface, a first parameter; receiving, via a receiver, a plurality of signals; generating a channel impulse response from the plurality of signals; selecting a portion of the channel impulse response based on the first parameter; generating a modified signal from the portion of the channel impulse response, wherein the modified signal is the portion of the channel impulse response with clutter removed; generating a plurality of regression lines from the modified signal; computing a plurality of times based on the plurality of regression lines, wherein each of the plurality of regression lines goes through zero at one of the plurality of times; estimating a zero-crossing time based on the plurality of times; and generating a breathing rate estimation based on the zero-crossing time.
