Subject: | Re: [Discuss-gnuradio] How to calculate BER in different modulations with OFDM using GNURadio Companion |

The configuration to which I refer in the previous email is the corresponding to the image attached2015-08-31 13:18 GMT+02:00 ANTONIO TAMAYO <address@hidden>:Hello,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 it is. 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.Thank you all.
