[Discuss-gnuradio] Calculate BER in WIFI 802.11p standards !

[Mériem Saïdi]

Hi,

I use 802.11 IEEE standards to code and decode a PMT message and i would like to calculate the BER between the source of information I want to encode and the same source after decoding. (see attached screen-shots below)
Except that I have all time a null BER ! however the "channel model" block introduce noise so the BER can't be null!
I've tried with a Random Source instead of Message Strobe but always the same result !
I don't know if the problem comes from one of the encoding/decoding flowgraph, or from the position of outputs i took to calculate BER ??!!
any ideas please ?!

Cheers,
Meriem.
