Re: [Discuss-gnuradio] BER and OFDM

Hi,

Some time ago I also tested this ofdm_loopback file and i figure out that is good to use additional noise source (simulate the channel but also add AWGN).

I don't know if this is a proper way of simulating OFDM Tx/Rx but it can be some hint.

Best regards,

With an Eb/N0 of 30 dB, that's what I'd expect. For other cases, I don't
think your setup works, because of the packet-based nature of the OFDM
transceiver (what happens if the demod doesn't find a packet?).
