The topic at hand is the digital predistortion of a non-linear RF power amplifier with memory effects. In order to achieve this goal, we will be simulating a DPD technique linearization for an AB-class nonlinear HPA with memory effects using M code. To accurately model the nonlinearity characteristics and memory effects of the HPA, we will be utilizing a memory polynomial predistorter.

The simulation procedures can be broadly divided into three separate parts. Firstly, we will be compensating for the analog imperfections that may arise in the direct upconversion transmitter. Secondly, we will be designing a DPD based on the memory polynomial predistorter that we have chosen. Finally, we will be evaluating the performance of our simulation by analyzing a number of parameters such as EVM, PSD, and SNR.

It is important to note that the results of this simulation can be incredibly useful for a number of different applications. For example, in the field of wireless communication, the ability to predistort the signal of a non-linear RF power amplifier with memory effects can significantly improve the quality of the transmitted signal. With that in mind, we believe that this simulation has the potential to contribute greatly to the field of wireless communication.
