The application of digital predistortion in base-band
signal is an extended method of amplifier linearization
to reduce the Adjacent Channel Interference (ACI) in
those systems in which a varying envelope modulation
scheme is used. This paper propose a particular
predistorter configuration and presents some design
considerations and simulation results in relation with the
use of fixed point Digital Signal Processor (DSPs). Less
than -60 dB out-of-band emission can be obtained for a
narrow bandwidth system.
