Resumen:
This paper presents a neural network-based behavioral model for accurately
reproducing the nonlinear and dynamic behavior of new wireless communications
devices. Moreover, an efficient procedure to extract a behavioral Volterra model from
the parameters of the NN-based model is explained, thus providing a simple way to
construct very compact and accurate models, which may provide open information
about device performance. Experimental tests try to demonstrate the validity of the
proposed approach, for characterization of RF transistors and power amplifiers, showing
strong nonlinearities and memory effects in the analyzed bandwidth.
