Thank you, Actually, I'd like to perform a 'quite' simple experiment consisting in assessing the runtime of a basic OFDM receiver running on FPGA (i.e. RFNoC) when processing an OFDM symbol (sent through a loopback cable). Searching the web, we got the impression that there is a version of RFNoC containing all blocks we need for that experiment (our team acquired X310 recently) [1]. In summary, is there any git TAG/version of the uhd/RFNoC repo that I can fetch to get the RFNoC OFDM Receiver blocks demonstrated in [1]? Thank you in advance,
best regards [1] Building an OFDM Receiver with RFNoC, 2015.
