Linearization of Rf power booster by utilizing pre distortion technique of polynomial digital memory

In modern wireless communication systems, new modulation has been formed to support the number of users that are utilizing spectral efficiency that is resulting in the occurrence of novel modulation techniques such as OFDM. output signals of this kind of novel modulation are usually in normal peak amount that causes the system to function nonlinear. The main part in the system, which makes it nonlinear, is the strengthener of its power. In power developers, linearity has inverse connection with efficiency. It means that If we want to endeavor for the linearity of the strengthener, we will be forced to lose the efficiency of it. However, both efficiency and linearity can be achieved in the strengthener by using distortion techniques. In this article, several distortion methods are investigated and digital distortion with polynomial memory has been studied due to its numerous advantages.
