AWR1642：How can I use MIMO mode in mmwave studio when I use DCA1000 to capture AD data?

Hello!

Recently I was using DCA1000 to capture AD data in AWR1642.

How can I use MIMO mode in mmwave studio when I use DCA1000 to capture AD data?

    Hi,

    That's right option. In the chirpConfig you need to select different Tx antenna for different chirp index. And then in the frame you need to set the chirp start and end index to generate the MIMO configuration.

    Is the default TDM mode?

    How can I set the chirp start and end index to generate the MIMO configuration.

    You need to use rlSetChirpConfig mmwavelink API to set a different set of chirp setting having each different chirp index. Selection of TDM and MIMO can be based on Tx antenna selection in the same API for each consecutive chirps.

    Please refer this API detail in rl_sensor.h or follow mmwavelink doxygen document (C:\ti\mmwave_sdk_03_02_00_04\packages\ti\control\mmwavelink\docs\doxygen\html\index.html).

    Then while creating a frame you need to select set of chirps which comprised in this frame, use rlSetFrameConfig API, where in rlFrameCfg_t structure you need to range of chirp for this frame.
