Power amplifier modeling using memory polynomial with non-uniform delay taps

In this paper, a new power amplifier (PA) model with memory is proposed. The new PA behavioral model is based on memory polynomial (MP) function with non-uniform time delay taps between instantaneous and previous input signal of the PA. This new method gives better error reduction than a MP function...

Zusammenfassung:In this paper, a new power amplifier (PA) model with memory is proposed. The new PA behavioral model is based on memory polynomial (MP) function with non-uniform time delay taps between instantaneous and previous input signal of the PA. This new method gives better error reduction than a MP function with uniform time delay taps. Simulation results for both types of PA models will be compared to show the advantage of the developed model.
