Sanjay Sharma, 'Fast complex Memory Polynomial based Adaptive Digital Pre-Distorter', International Journal of Electronics, Vol. Key words: AM/AM characteristics, Digital Predistortion (DPD), Memory polynomial, Power Amplifier (PA), Power Spectral Density (PSD). The presented technique is easy to implement and simple. So in this paper, a digital predistorter based on memory polynomial has been proposed that takes care of above mentioned issues. But due to the issues like memory effects and exact characterization of non-linear behaviour of power amplifier, the implementation of existing predistortion technique suffers. The various types of linearization techniques are available for linearising PA but Digital Predistortion technique has been observed as one of the most common and effective method. Abstract: Linearization of power amplifier has been an area of intense research from the last many years.
