OFDM using DSP Builder

Hi, I'm trying to implement a simplistic (4 channel) QPSK OFDM transmitter/receiver using Altera's DSP Builder and Megacore IP in Simulink. Let me just mention that I have very basic knowl...

I also have a question related to this, if you are using the streaming architecture for the FFT block (we would use it here wouldn't we?), should we be using the Avalon-ST interface?

I don't quite understand the Avalon-ST, and all the examples I found on the web are from Quartus II, not DSP Builder.

And since the FFT (streaming mode) can only take a max of an 24-bit bus for the Real and Imaginary inputs, we cannot just simply concatenate the output bits after mapping the symbols to their real and imaginary parts, how can this be solved?
