Other Parts Discussed in Thread: DCA1000EVM, AWR2944, AWR1843

Tool/software:

Hi,

I’m using AWR1843BOOST + DCA1000EVM to capture raw data. I know TDM-MIMO is supported, but I wanted to check:

Does AWR1843BOOST support BPM-MIMO (the BPMConfig tab shows up in mmWave Studio)?
Is there any way to enable CDMA or DDMA on this device, or are these features only available on newer radars like AWR2944?

Thanks a lot for your help!

Best,
Zahid

Yes, it is supported. You can refer to previous discussions on this forum for reference. Here is one of the E2E that you can check - (+) AWR1843: Is there a possibility of BPM transmission for 3Txs - Sensors forum - Sensors - TI E2E support forums.

Yes, you can use DDM configuration with AWR1843. You can configure per chirp Tx phase shifters which is needed for DDM configuration in AWR1843.

Note: Post processing available in mmWave Studio won't support DDM configuration.
