Problems running tx_ofdm and rx_ofdm

GNU Radio

Hey,

i changed tx_ofdm and rx_ofdm to communicate through a fifo (named
pipe) instead of USRPs
and i seem to have problems making them work.

It seems that when rx_ofdm starts one of the threads goes to 100%
but nothing comes out of the debug_tag block at the end of the
receiver, which indicates nothing is demodulated…

BTW, is the Schmidl&Cox symbol-spaced?

thanks
Achilleas

PS: this is a really clean RX design with tags! Thanks!

I’m seeing something similar. Somewhere, a block is spinning. I’m
working on it.

Say again?

Glad you like it!
