Abstract

A detailed RF modeling and analysis for the effect of the phase noise of the local oscillator (LO) on a 60-GHz wireless non-contact human vital-signal detection system has been developed. To model the effect of the LO phase noise on the remote detecting estimation of the desired breathing and heartbeat signals around 1 Hz, the Lorentzian spectrum is applied for the RF system simulation of detection process. The simulation uses the root-MUSIC algorithm to calculate the frequency error ratios of the estimated heartbeat and breathing signals by the detection system. From the simulation results, it is found that root-MUSIC method is robust to analyze the effects of different phase noises on the non-contact vital-signal detection. The simulation result will be very useful for the RF design specifications of the wireless non-contact human vitalsignal detection system.
