Abstract

This paper presents a respiratory rate monitoring sensor using stepped-FM ultra-wideband impulse-radio (UWB-IR), which does not require high speed A/D devices unlike conventional UWB-IR sensors. This sensor is also capable of co-existing with other narrowband systems operating in overlaid frequency band, since it can be designed to have any spectrum hole without causing interference with other wireless systems. The set-up has been fabricated where the algorithm detecting the respiration rate and other movements are developed. Please note that the A/D used in the set-up of 1GHz UWB is 10ks/s. It is found from the measurement results that the stepped-FM sensor is useful to detect the respiration rate and various movements without causing the other narrowband system.
采用步进调频的远程呼吸监测传感器
本文提出了一种采用步进调频超宽带脉冲无线电(UWB-IR)的呼吸速率监测传感器,它不像传统的UWB-IR传感器那样需要高速a /D设备。这种传感器也能够与其他窄带系统共存,因为它可以被设计成有任何频谱洞,而不会对其他无线系统造成干扰。在检测呼吸频率和其他运动的算法开发的地方,已经制作了这个装置。请注意,在1GHz超宽带设置中使用的A/D是10ks/s。测量结果表明,步进调频传感器可以有效地检测呼吸频率和各种运动,而不会引起其他窄带系统的干扰。
