Upgrading Behavioral Models for the Design of Digital Predistorters
(MDPI AG, 2021)
This work presents a strategy to upgrade models for power amplifier (PA) behavioral modeling and digital predistortion (DPD). These incomplete structures are the consequence of nonlinear order and memory depth model ...

Formal deduction of a Volterra series model for complex-valued systems
(Elsevier, 2017-02)
This paper demonstrates a general model for nonlinear systems with complex-valued inputs and its application to communication systems modeling. Based on Wirtinger calculus and a double Volterra series approach, the proposed ...
