I’m doing my College final project about gnuradio companion.
I have to calculate the BER with OFDM using different modulations to the
subcarriers. After that, I have to do a graphic with the BER numbers.
configuration I use is in the image attached.
When I’m using GRC to calculate BER I always have the same problem.
try to simulate without introducing any noise and get a BER data. Then I
try to introduce AWGN noise and the BER data is the same. Clearly I’m
making a mistake, but I’m not able to identify what it is. In view of
configuration used, someone could tell me which are my mistakes?
Also, I would like to know how to configure the block Channel Model
Thank you all.
