Hi,
I was just testing the transmission of an OFDM signal through an URSP2
and using another USRP2 to receive it.
I noticed that a carrier was present in the OFDM signal’s FFT. Is it
supposed
to be this way for OFDM? I mean, when we put a signal on the RF we are
just changing its center frequency, not inserting a carrier. I
suppose…
I would be grateful if you clarified this for me
