Abstract
An improved adaptive Least Square (LS) algorithm using QR (orthogonal and upper triangle matrix) decomposition for digital predistortion (DPD) is presented in this paper. Compared with the traditional LS algorithm, this new method is featured by low complexity and high efficiency. Simulation results show that this adaptive LS algorithm using QR decomposition can significantly reduce the complexity and therefore, is ease of implementation.
