Abstract
In this paper, we demonstrate a nonlinear
autoregressive with exogenous input (NARX) DPD technique
which is more compact, less computationally intensive and less
susceptible to errors caused by noise in the PA output compared
to an equivalent memory polynomial based DPD. Experimental
validation is performed with a 20 MHz LTE signal for a GaN
Doherty power amplifier.
