Hi, I am currently working on a project "Non Contact Vital signs Monitoring System". I am using a 24Ghz radar IF signal to extract the heart rate and respiration rate.

Algorithm is

1. Output signal from the radar is given to A/D converter and sampled at 100Hz

2. Then signal is amplified

3. Output of amplifier is given to bandpass filter, For cardiac monitoring filter was set between 0.5 Hz and 2.5 Hz. For respiratory monitoring, the

filter was set between 0.05 Hz and 0.5 Hz

4. After band-pass filtering, each signal was processed by a Fast Fourier Transform (FFT) using a Hanning window

5. The result from the FFT conducted for each signal from the respective microwave radar after band-pass filtering set at between 0.5 Hz and 2.5 Hz was

multiplied 2) the frequency of the peak signal between 0.5 Hz and 2.5 Hz was assumed to correspond to heart rate. The same analytical process was

conducted between 0.05 Hz and 0.5 Hz to calculate respiratory rate

I want to develop a simulink model for this Algorithm and I am new to signal processing. I got this algorithm from IEEE paper i don't know to how extent this will work.

I need help in building this algorithm. I need help mainly in design simulink block 4th and 5th step in algorithm. It would great if someone could provide me a simulink block file for this algorithm
