ABSTRACT:
An adaptive predistortion arrangement includes means (26, 40, 42, 44, 46) for up-converting a baseband signal (S1) into an intermediate frequency signal (S12) having frequency aliazing and means (18, 20, 220, 24, 26) for down-converting a radio frequency signal (S4) into an intermediate frequency signal (S7) having the same frequency aliazing as the up-converted baseband signal. An adapter (34) adapts predistortion parameters to keep the up-converted baseband signal equal to the down-converted radio frequency signal.
