M. Visintin, AN ADAPTIVE DSP PREDISTORTION TECHNIQUE FOR RADIO SYSTEMS, European transactions on telecommunications and related technologies, 5(4), 1994, pp. 509-515
A simple implementation of an analog predistorter for nonlinear HPA is
described. Good performance is obtainable in terms of BER, and bandwi
dth occupancy of the signal after the amplifier. The described techniq
ue is independent of the modulation format and of the filter character
istics. Results are given for 16-QAM and 64-QAM modulation schemes.
