Dear Samie, Good to know you are working on PHY/MAC layer of OFDM signal like LTE and wifi on the USRP. I'm also want to deploy the PHY layer of LTE on USRP but trying to use RFNoC. I got a little bit confused about the PHY layer of WARP project targets on Wifi, 802.11 standard rather than LTE. Could you tell me can I use the same PHY layer from WARP to process the LTE signal? Because some different points between OFDMA and OFDM like cyclic prefix length, FFT length.... Thanks for your help.
