[Discuss-gnuradio] Non-deterministic behavior

[Vanessa Gardellin]

Dear all,
we are experiencing an undesired random behavior when we run an
offline OFDM flow graph.
Specifically, we store a transmitted sequence of packets in a *.dat
file (file_sink) and then we run the receiver chain using always the
same file as source (file_source).

Repeating several times the same run using the same source file, we
get a varying number of received right/wrong packets.

Is there an explanation to this behavior?
How can we generate a repeatable experiment?


Regards,
Vanessa
