Desging a mimo_ofdm in RfSoc 4x2

hello,
I am using the RFSoC 4x2 with PYNQ, and my interest is in designing a MIMO-OFDM system starting with the provided RFSoC_OFDM example. I am very new to using the RFSoC 4x2 and would appreciate any guidance or resources.

Specifically, I would like to know if there is an available example for MIMO on the board or any desgins that can help me move forward. Any pointers in the right direction would be greatly appreciated.

Thank you!
