Hello，

1. I configured mmWave studio to use mimo mode, two send and four receive. As shown below:

Is cdma code or ddma code used in mmWave studio? I don't see it on the screen
2. After MIMO is adopted, what is the format of the data collected by dca1000?

As shown in the figure, RX0 received the data of TX0 and TX1 at the same time, may I ask whether they put all TX0 in the memory first and then put the data of TX1? Or how is it organized?

Regards，

Gary
