vital signs config for mmwave studio !

Other Parts Discussed in Thread: AWR1642, AWR1642BOOST

Hi all,

I am trying to apply the same vital signs configuration file into mmwave studio and get AWR1642 radar raw data as an output. I am a bit confused about the configuration that should take place in mmwave studio to record raw radar signals which allow me to g ofurther for a vital signs extraction from this raw data.

my fisrtquestion is: should the signal be a complex signal or real signal ? because in the vitalsignslab config file, the adcCfg is: (2,1) which means that the signal should be complex one? in mmwave studio log file, I have the equivalent config like this : AdcOutConfig (2,0,0), which means it is recording real signal!

my second question is about the ChannelConfig parameter: in vital signs lab, the ChannelCfg parameter is set to (15,3,0) which means using and 1 Tx and one Rx ? in mmwave studio, from the log file, the channel conf parameters is: ChannelConfig,1,15,0.

and in the datacapturedemo.lua file, I am setting the channNadcConfig as follows: (1,0,0,1,1,1,1,2,0,0) which means using one tx, 4rx, single chirp, 16 bits, and the (2,0,0) means that the signal to record is real!

I am confused between what the vitalsigns lab conf says, and when trying to apply it on mmwave studio, it seems to be not similar...

thanks in advance,

Ahmed

Ahmed,

For your first question, the ADC output format is complex 1x. For your second question, all four RX antennas and both TX antennas are enabled. Only when we get to the actual chirp configuration do we specify the number of TX antennas that are turned on for the actual chirp.

Please adjust these parameters to match your implementation in mmWave Studio.

Regards,
Kyle

Hi kyle,

So the vital signs lab uses a complex 1x raw radar signals to extract the vital signs! Are they somehow mixed together (real and img parts of the signal) for the vital signs extraction?
Thanks again for your response.

kyle,

attached, I uploaded the two conf files: the first for vital signs lab itself, and the second for the mmwave studio conf. I tried to adjust the first conf file parameters to match my implementation in mmWave Studio..

can you take a look on it! am I missing something?

thanks,

Ahmed

Kyle,
concerning the first question, in the complex 1x data mode, what does each part of the signal means ! real signal is the transmitted ! and img signal is the received !
thanks,
Ahmed

Ahmed,

This understanding is not correct. Please refer to this previous E2E thread about understanding the difference between complex 1x mode and complex 2x mode.

Please keep in mind that the vital signs extraction is done on the DSP of the AWR1642BOOST EVM. It is not just the raw signal itself that gives the vital signs information. This is achieved primarily in software and not in hardware. Attempting to use mmWave Studio and just copy the profile configuration from the vital signs demo is only one aspect of this lab. I would suggest reading through the User's Guide that is included for this lab to get a better understanding of how this lab actually works. All of the source code for this lab is provided on TI's Resource Explorer.

Regards,
Kyle
