Hello Cédric, Hello everyone
Thanks for your replies. I will try to use or be inspired by those blocks.
I have a slightly more specific question on this subject. Do you know
how to integrate the codes in the fpga/usrp3/lib/blocks/rnfoc folder
into a new OOT block/module? Do you instantiate them in the same way as
the ‘mult_rc’ IP (the one in the "HDL_IP" parameter) in the example of
the gain module? To structure the code, is it possible to define how to
move this code within the OOT block?
Thanks for your help, I appreciate.
Quentin

As part of a research project, I'm looking to implement an OFDM receiver on
the FPGA of a USRPx310 (and more specifically, the synchronisation stage).
According to my research, some RFNoC blocks with this function already
perform this function. Where can I find them?
AFAIR, there are some RFNoC blocks in a branch over the old FPGA repo:
https://github.com/EttusResearch/fpga/tree/rfnoc-ofdm
for example:
https://github.com/EttusResearch/fpga/blob/rfnoc-ofdm/usrp3/lib/rfnoc/ofdm_peak_detector.v
Apart from Schmidl&Cox, I don't see anything merged into the default branch.
Never used them. Don't know how accurate they are.
Note that they are 7-8 years old...
Best
