I want to realize a simple BER test using OFDM instead the modulations options in the original bert_simulator.grc. I thought that a simple change would work. Basically, I remove de mod/demod used in change for OFDM Mod/Demod.
However, when I run the flowgraph, after I few seconds (3 at max) the flowgraph hangs.
Does anyone know how to solve it?
The .grc file modified is attached.
