Hi, Marcus.
Thanks for the reply. I use antennas for the transmitter and receivers,
I forgot to mention I use two N210 USRP platforms with WBX
daughterboards. When the transmitter is off, there is no other signal in
that frequency band. I believe I should try to make an advanced tuning
in order to set an offset for the local oscillator, that might eliminate
the spurious component. What other methods can I use in order to
eliminate the spurious components? Is a band-pass filter at the receiver
a good option?
