How would that work? For the 100 MHz sampling A/D, would you sample at baseband, and then run 2x 50 million point FFTs, 10 times or more per second? Can the Spartan-3 DSP do that?
It sounds like you got a fantastic deal on Matlab, from your other message. I think they intended you to do great things with it, maybe help me build a 2 chip radio. ;) In regards Verilog, I would be pleased if you would play Professor, and guide my learning down a path that leads to a HardRock 1.0 a year from now.

Q's about Xilinx DSP FPGA Leon's suggestion of using a Linear Technologies high speed direct sampling A/D is a good one, the FPGA board should be able to handle the data rate and conversion, when you are finished you will have a very versatile radio. ... It's just a though if you had the software it could be used to generate DSP blocks for you in conjunction with the Xilinx software, you could test the algorithm in MatLab and once it works right turn it into a library module to use in the project, such things as decimator's, filters, FFT modules. Once done the would be available for use by anyone without the need for MatLab unless they want to change it. ... Are you going to use Verilog? I have been playing with it a little bit and it's not too bad. The Xilinx software is fairly nice.
