Hi Sarah - Glad you're heading down a positive path. The header data is removed from the raw data being decoded, but added as meta-data on the stream. This meta-data is optionally printed out by GR OFDM and/or various Qt displays. Once the header has been verified (via CRC8), it is no longer part

Hi Sarah - A few things to note on using the default GR OFDM using real SDR devices that could be relevant here: * tx data amplification: This needs to be such that the data heading to UHD doesn't saturate on conversion. You can visually see this if you look at the raw Rx signal ... it will

Hi all, I am trying to use the ofdm_tx.grc and ofdm_rx.grc to transmit data from one N210 controlled by a host to another N210 controlled by a separate host. Eventually I want to build an 8x8 MIMO system using OFDMA. I want to verify that the correct data is being received so I sent all of the
