Compiler/IWR1843: What is the mode of transmitting antenna in mem capture

Part Number: IWR1843

Tool/software: TI C/C++ Compiler

Using MEM capture is TDM mode or BPM mode under three transmit antennas. Where can I see this? Can I modify the settings? I don't see the settings in the MSS. C file

  • Hi, 

    I see following functions inside mss.c:

    static void MemCapture_initLinkProfileCfgParams (rlProfileCfg_t* ptrProfileCfg);
    static void MemCapture_initLinkChirpCfgParams (rlChirpCfg_t* ptrChirpCfg);
    static void MemCapture_initLinkFrameParams (rlFrameCfg_t* ptrFrameCfg);

    The current configuration is only for one TX antenna.  And you will need to change the code to support TDM-MIMO or BPM as you wish.

  • Can you tell me which code needs to be modified, not in mss.c? Can you tell me the specific documents?

  •  I have set up and started 3 TX 4RX, but I don't see the settings about BPM and TDM in MSS. C. I hope you can tell me more about the specific steps.

  • HI, 

    For TDM-MIMO, you need to call those three functions sequentially to achieve a similar configuration in SDK out-of-box demo.  

    profileCfg 0 60.00 6 6 50 0 0 45 1 256 6000 0 0 48

    chirpCfg 0 0 0 0 0 0 0 1

    chirpCfg 1 1 0 0 0 0 0 4
    chirpCfg 2 2 0 0 0 0 0 2
    frameCfg 0 2 32 0 200 1 0

    To understand these parameters, you can search "profileCfg/chirpCfg/frameCfg" in SDK user's guide located at: C:\ti\mmwave_sdk_03_03_00_03\docs

    For BPM feature, the SDK out-of-box demo only support 2 TX BPM, you can search bpmCfg in the SDK user's guide and search SDK demo code to see how it is implemented and come up with your own solution to implement 3 TX BPM.   That is all I can help with.

    Best,
