Abstract

This talk explores the application of Multiple-Input Multiple-Output (MIMO) radar technology for noncontact vital sign monitoring, utilizing a 77-GHz Frequency Modulated Continuous Wave (FMCW) system with 192 Time Division Multiplexing-MIMO channels. Originally developed to enhance data transmission rates and network capacity in wireless communications, MIMO technology is adapted here to improve the accuracy and reliability of remote heart rate (HR) and respiratory rate (RR) monitoring. We employ advanced signal processing techniques such as Maximal Ratio Combining (MRC) and Continuous Wavelet Transform (CWT), alongside a convolutional neural network (CNN) for automatic channel classification, to enhance the precision of vital sign detection. Experimental results demonstrate significant improvements in HR estimation accuracy, with over 20% reduction in root-mean-square error (RMSE) compared to traditional methods. These findings highlight the transformative potential of MIMO radar systems in medical diagnostics and remote health monitoring, offering robust, non-invasive solutions for continuous and accurate vital sign measurement.
