DDC design

hi all,
I am trying to design my own DDC for the purpose of better reception of
gsm
signals, but stuck with its design, currently I am using vertex 5 FPGA
from
Xilinx, so please if there is any link or design guide from where we can
start, Any help is very much appreciated.

Are you getting stuck with the FPGA/Verilog portion, or the signal
processing “what do I do?” portion?

For the FPGA/Verilog stuff, it isn’t too bad - just ask the right
question and there should be an answer somewhat quickly.

For the signal processing “what do I do?” stuff, you should try that
book Bob McGwier posted about earlier:

Looked like it has some good SDR material in it. I am sure they go
over mixers and DUC/DDC and plenty of filtering.

Good luck!

Hi Brian thanks for reply, right now we are stuck with DDC
