Hi all,
Two months ago I shared with you the following message:
"I'm doing my College final project about gnuradio companion. Specifically 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. The configuration I use is in the image attached.
When I'm using GRC to calculate BER I always have the same problem. First I 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 is it. In view of the configuration used, someone could tell me which are my mistakes?
Also, I would like to know how to configure the block Channel Model correctly."
In that moment I was using an old version of GNURadio Companion, 3.2.2, now I'm using 3.7.1.2 version and I still have the same problem. Please, could someone tell me which are my mistakes? I would like to be informed of how to set the parameters of the blocks I used.
Also I share with you the gnuradio Companion configuration file I've used in which the block diagram is displayed, the image I've used to calculate the BER and the results I get when I run the diagram.
Thank you all,
Antonio.
