Hi
I m using USRP2 and USRPN210 DB RFX900.
Block diagram
MOD:random source-->ofdm-->usrp sink
DeMOD:usrp source-->ofdm demod-->>sink scope,fft
Problem is that:
Modulation is going fine,even at the receiver end the spectrum is just like
it should be (block for OFDM )
but there is nothing at the output of OFDM demod block Sink Scope is showing
nothing. <http://gnuradio.4.n7.nabble.com/file/n38053/OFDM_DeMOD.png>

<http://gnuradio.4.n7.nabble.com/file/n38053/Spectrum.png>
I have attached the mod,demod,received spectrum snaps.
Help is highly appreciated...:-)
