Just wondering - how much bandwidth do you need? If you are going to run with a fixed amount of decimation for all of your tests, you can change the FPGA's CIC to have a fixed value and bypass the halfband filter if you want. This will free up a SIGNIFICANT amount of space in the FPGA to perform filtering, equalization, and other processing. The default build allows for some serious decimation, and a LOT of options for general SDR. For more specific purposes, use the sdr_lib to your advantage, make your custom chain, and write the rest of your custom FPGA load. I am no expert, but I believe the USRP samples 4 real or 2 complex channels at 64MHz. Is there reason to believe this is not enough bandwidth?
