Simplified Memory Polynomial modelling of Power Amplifier

Accurate Power Amplifier modelling is of major concern for wireless communication system designers. Volterra series is most suitable to represent the actual behavior of non-linear power amplifier with memory. But as the order of memory polynomial increases, the number of Volterra terms also increases, resulting in the implementation complexity of Volterra series. The Memory Polynomial model, which is reduced form of Volterra series is most widely used by researchers but is complex to implement. The identification of coefficients of Memory Polynomial is also a tedious task. So, in this paper a simplified and easy to implement form of Memory Polynomial model of power amplifier has been proposed.
