Power Amplifier Linearization using Singular Value Decomposition Algorithm

Abstract

The power amplifier presents itself as a significant device towards the improvement of system. But itself it is the main source of nonlinearities present in the transmission chain. This effect is appropriate as it produces a spectral regrowth consequently leaking energy into adjacent channels. To improve the power amplifier efficiency without compromising its linearity, power amplifier linearization is essential. A common solution to avoid this effect is to drive the PA far from its compression zone, a technique known as back-off.
