Re: [Discuss-gnuradio] OFDM with noise - lost packets

I need to check the loopback flowgraph you mentioned, but the header detection should work down to very low Eb/N0 values. However, you mention a noise amplitude of 1.5. IIRC, that would yield an SNR below 0 dB, not 13 dB as you mention. Cheers, Martin On 19.12.2015 17:41, Mateusz wrote: > Hello

Hello, I have been evaluating the OFDM examples (at the beginning of my Bachelor Thesis) In ofdm_rx I have added noise source and file sinks to plot BER(SNR) in matlab. I added a Tag Debug on the output. The result is disappointing, I observe plenty of lost packets already at the SNR of about 13
