Ah cool. Can you point me to papers/text showing how the n-th harmonic
is being removed from the spectrum?
SDRs provide the greatest flexibility but unless
you have specific
RF filters in your frontend you will not pass the harmonized norms
of the European Union for GSM.
I think this statement is quite dated. A calibrated USRP N200 running osmo-trx passes RF
spectrum and
modulation accuracy requirements of 3GPP 05.05 by very large margins
and is competitive with commercial GSM equipment in this regard. Other
SDR devices are also capable to varying degrees.
The policy of FCC vs. European Union is quite different. There are more
norms that apply in Europe.
