Digital predistortion of power amplifiers using structured compressed-sensing Volterra series
(The Institution of Engineering and Technology, 2017-01)
Digital predistortion has become an attractive technique for power amplifier linearisation whose limiting factor for using Volterra series as the underlying model is its computational complexity, since the number of ...

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 ...
