Re: Working with the OFDM code without USRPs

I got the reason of the problem: that was because of the slightly
different software version of the gnuradio that I had at each side.
After I matched the software versions, it worked correctly almost as
expected.
About the problem, I got that for free by making the below substitutions
in the flowgraph.
Thanks.

You need to ensure that the data written to the file is at the same
sampling rate as is expected by the other program. I’m not sure if
you get this for free by making the above substitutions in the
flowgraph.
