abstract = "This paper presents a genetic programming (GP)
approach enhanced with a local search heuristic (GP-LS)
to emulate the Doherty 7 W @ 2.11 GHz Radio Frequency
(RF) Power Amplifier (PA) conversion curves. GP has
been shown to be a powerful modelling tool, but can be
compromised by slow convergence and computational cost.
The proposal is to combine the explorative search of
standard GP, which build the syntax of the solution,
with numerical methods that perform an exploitative and
greedy local optimization of the evolved structures.
The results are compared with traditional modeling
techniques, particularly the memory polynomial model
(MPM). The main contribution of the paper is the
design, comparison and hardware emulation of GP-LS for
FPGA real applications. The experimental results show
that GP-LS can outperform standard MPM, and suggest a
promising new direction of future work on digital
pre-distortion (DPD) that requires complex behavioural
models",
