In the MIMO-OFDM, there is a simulation only OFDM model as mentioned in http://warp.rice.edu/trac/browser/Resea … /MIMO_OFDM , but the link is missing.
Could you please provide the correct link to these documents?

The OFDM PHY documentation is still a work in progress; the missing sections aren't written yet. I hope to get them done soon.
The simulation only model was deprecated a while back. The current OFDM models are useful both in simulation and hardware.

Thanks for the details.
I am trying to build the MIMO-OFDM system using the following WARP provided MATLAB source files:
ofdm_txrx_mimo.mdl, ofdm_rx_mimo_init.m, ofdm_tx_mimo_init.m, ofdm_rx_init_packetTimingControl.m, CRC_table_gen.m, and calcTxCRC.m.
In the sysgen pcore generation process I want to use my own system.xmp file. Once the pcores are generated from sysgen, then I will take the design to EDK and add MAC codes to the design and generate bit stream. Could you please comment on the correctness of the process?
What special things I need to take care in the above process?
What is the BRAM interface block in the simulink model and how it is interacting with the simulink TX and RX flow?

That's the correct general flow. The second workshop exercise illustrates the full flow for a much simpler design.
Please keep in mind that after following the same steps for the OFDM PHY (and other PHY peripherals), you will have re-created the hardware design for the OFDM Reference Design.
The OFDM reference design uses a PLB_bram core for a packet buffer. The PHY's BRAM interface subsystem implements the top-level ports and byte-steering logic to interface with the PLB_bram instantiated in the EDK project. This design component was discussed in some previous posts (here and here).

Thanks for the clarification.
