Abstract
The objective of this research is from radar life parameter monitoring system for respiration and heartbeat signal separation, therefore the characteristic parameters of respiration; heartbeat could be extracted to provide the basis for family care and disease prevention. This paper put forward a method to analyze the characteristics of the echo signal, improve adaptive filter harmonic combination of reference input signals for respiration. Home monitoring results for simulation experiment is proposed based on LMS adaptive harmonic cancellation algorithm for adaptive filtering. Conclusion in the home monitoring experiment can effectively separate the respiration and heartbeat signals. DOI : http://dx.doi.org/10.11591/telkomnika.v12i4.4777
