Hi, guys
Thanks in advance.
I plan to do a experiment in usrp that intentionally adding some
frequency offset in data symbol before transmission. Is that feasible
to implement it in gnuradio? Which block should I modify at sender
side?
Quite easily and in a few different ways. You can use the Channel
Model block and just set the frequency offset and nothing else. You
can use a frequency xlating filter, or you can do a complex multiply
of your signal against a complex sinusoid.
Just remember that you need to have a high enough sampling rate to
accommodate the bandwidth of your new signal.
