carrier frequency is centered correctly on the receiver and that the

you go to higher tone spacing it is more tolerant of the higher
frequency error, and that is why it works.What you need to do is modify the code to search for the signal over a
wider frequency band.
I thought I took care of this by manually centering the spectrum (I do
this at every frequency). I do this:
1.Launch the OFDM transmitter at 400MHz
2.Launch a receiver at 400MHz with a GNU Radio fft-sink and write down
the constant offset (say 400.021MHz)
3.Launch the OFDM receiver at 400.021MHz
So the OFDM signal is centered perfectly, but still I only receive
broken packets. Or do you mean something else? Is the narrow band OFDM
signal maybe distorted in some fashion and at >400MHz can not be
properly recovered anymore?
Or use the wider tone spacing.
That is a perfectly valid solution that works 100%, but actually I am
just wondering why the narrow band transmission that works fine at
<100MHz does not work anymore at >400MHz.
