Abstract

By analyzing the input and output data of memoryless power amplifier (PA), we construct the polynomial model and study the nonlinearities characteristics of it. Based on that the mathematic model of predistorter is gained, Least-square (LS) and adaptive LMS are used respectively to solve the question. Simulation results demonstrate predistortion can effectively correct the nonlinearities and both LS and LMS work well depending on different conditions.
