雷达式非接触检测中呼吸和心跳信号分离算法的研究
Study on the Algorithm for Separation of Heartbeat and Respiratory Signals Based on Radar Non-contact Detection
摘要
Abstract
In order to separate the breathing and heartbeat signals from biological radar effectively so that the physiological characteristic parameters (respiration rate and heart rate ) can be real-time monitored, this paper proposed a LMS adaptive harmonic cancellation algorithm by extracting the harmonic combination of the respiratory signals as reference input and the body motion signals detected by biological radar as original input based on adaptive noise canceller. Simulation results showed that breathing and heartbeat signals can be separated in real time with the proposed algorithm which is simple and easy to be implemented.关键词
