Hello There. Your implementation for the model in very impressive. Did you came to the fixed point hardware realization in one shot ?? Were there no intermediate steps ? That is to say, do you have a floating point equivalent model of the system, that can be run, without the xilinx system geenrator, and we can make changes for optimization. That would be a great help.
Lastly. can you please refer to a paper, or an implementation white paper, which you guys followed while implementing this entire model. Even a set of references will do, so that we can correlate a little.

The Sysgen fixed-point implementation is the only version of the model we built; we don't have a floating point or m-code version.
We used a few papers early in the design to understand parts of the synchronization requirements in an OFDM receiver (links below). But we figured out the overall architecture from scratch.
