Tool/software: Code Composer Studio

Hi

I'm using the IWR6843AOP and AWR1642 to work on the Vital-Sign detection. I have studied all documents which were provided in toolbox and the source code. But still some unclear understanding on those parameters. Can you guide me where I can find the meaning of each following parameter? or explain through this thread here? Thanks!

    Hi Jemmy,

    I would suggest you to go over the developer guide provided in the application package.

    Variable level of information may not be available and it may difficult for us also to provide that.

    Many of the variables here are the parameter/feature estimation, correlation which are required intermediate state while doing the signal processing to identify heartbeat and breathing rate. And later it creates a confidence matrix for each feature to get the almost matching no. as output.

    Regards,
