We study the performance of Hammerstein predistorters (PD) to model and compensate nonlinear effects produced by a high power ampliﬁer with memory. A novel Hammerstein model is introduced that includes, as the basic static nonlinearity, the complex simplicial canonical piecewise linear (CS-CPWL) description. Previous results by the authors have shown that the use of this kind of static nonlinearity leads to an efﬁcient representation of basic nonlinear models. Furthermore, different tradeoffs between modeling capability and performance are considered.
