CCS/AWR1443BOOST: AWR1443: Data format issues in TDM-MIMO mode

Part Number: AWR1443BOOST
Other Parts Discussed in Thread: AWR1443

Tool/software: Code Composer Studio

Hi,

I am currently studying the MIMO mode of the AWR1443, and I noticed that the device can be set to TDM-MIMO and BPM-MIMO mode. So I configured the AWR1443 into TDM-MIMO mode according to the configuration requirements shown in Figure 1. 

                                                                                                                                                      Fig.1

I analyzed the data after I got the data. I have some doubts about the data format in TDM-MIMO mode. I analyzed the data after I got the data. I have some doubts about the data format in TDM-MIMO mode.

That is, only when the device starts running in TDM-MIMO mode, only when the first antenna first acquires a chirp, the second antenna acquires the next chirp and then alternately collects all the data. Please tell me if I understand the data format in TDM mode correctly. At the same time, if your company has a data format document or picture description in MIMO mode, it is better. Thanks!

  • Hi,

    Based on your snapshot it looks like you are using LVDS transfer using the DCA1000 capture board.

    Please check the section "23.6 DCA1000 EVM capture format (xWR12xx/xWR14xx complex, 4 channel, 4 23.6lanes [Interleaved])"

    Thank you
