Abstract
The availability of fast and cost effective digital processing technology makes digital pre-distortion attractive for power amplifier linearization since it promises high power efficiency and flexibility. Digital pre-distortion task can be divided into three sub tasks: modeling of the power amplifier (PA), adaptive identification of the model parameters, and development of the pre-distorter. The memory polynomial model, which is reduced form of Volterra series, is most widely used by researchers. The accuracy of memory polynomial based digital pre-distortion depends on the memory depth and order of memory polynomial. In this work a generalized graphic user interface has been developed for modeling of power amplifier and digital pre-distorter. The memory depth and order of memory polynomial can be changed and experimentation can be done for different values of memory depth and order of memory polynomial.
