    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
