There is an error when I ran the rx_ofdm.grc in the GNURadio.
It give some information in the picture.
what should I do for this error?
We didn't develop that flowgraph, please understand that we can't really give you support for this.
That said, it looks like it's trying to create "tx-hdr.dat" file, and fails because it doesn't have the right to do so. Try to execute the Python script from a folder that has write access for your user.
