The paper presents a novel computationally and memory efficient structure of an HPA predistorter based on piece-wise linear approximation of the HPA inverse characteristics. The adaptation algorithm is derived and representative simulation results are presented showing good quality of the proposed HPA predistorter and its adaptation algorithm.
