Subject: | [Discuss-gnuradio] Calculate BER in WIFI 802.11p standards ! |
Date: | Mon, 17 Jul 2017 12:06:07 +0200 |
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.
