Understandable, but also remember that a CORDIC can perform a multiplication if you want it pipelined - and if you have a 64MHz clock with data coming out at 1Msps, you can perform a 64-tap FIR filter with only 1 multiplier instantiated. I can see where it is a concern, but it should be able to be circumvented relatively easily. I think a simple rake receiver might be possible at something like 1Msps and a 64MHz clock in that FPGA. > 802.11b (more specifically VoIP-over-WiFi), GSM (EDGE), and eventually 3G > (HSDPA) > waveforms.

I have not seen discussions with regards to those times, but I think GSM and HSDPA will be difficult strictly from an encryption standpoint. I thought the algorithms used for those protocols were under wraps and portions of the key are in your SIM card? As a curious note, why do you think there is a big push to do standards that are out there and already implemented efficiently in dedicated silicon? Do you have any intention on creating your own MAC protocol?
