Abstract
A novel low-rate identication method for high
power ampliers with memory-effect is presented. It is demonstrated
that the required bandwidth of the feedback signal is
not required to be greater than twice the signal modulation
bandwidth, but is instead determined by the number of feedback
samples and the degree of freedom of coefcients in the behavioral
model. As the experimental measurements and extracted power
amplier model show, this method can achieve a much better
NMSE accuracy of modeling power amplier with nonlinear
memory-effects compared with previously published approaches
