Hi. I am using an OFDM transmitter and receiver blocks from GNU radio. Essentially what i want to do is split up the bandwidth into 64 subcarriers and trasmit on any one of the subcarriers, say subcarrier 3. If that is to be done, in the data carriers field of the ofdm transmitter and receiver, mentioning just '3' as the subcarrier should work.
But somehow, that isn't the case. The receiver is not able to detect any received signal. Any suggestions what could the problem be?
