Error reduction of memory polynomial with binomial reduction in digital pre-distortion for wireless communication systems

The inherent character of the Power Amplifier (PA) on its non-linearity causes unwanted amplitude and phase distortions at the PA output signal. Faster information transmission speed together with the rapid changes in temperatures of electrical components incurs Memory Effects, the undesired spreadi...
