Abstract

Adaptive algorithm plays an important role in digital predistortion for the linearization of power amplifiers. In this paper, a new approach which uses least square (LS) adaptive algorithm with singular value decomposition (SVD) is presented. When calculating inversion matrix of power amplifier model, if combined with singular value decomposition, LS can not only excavate important structural information of the matrix, but also reduce the dimension of the matrix, and therefore, improve the stability and decrease computation complexity.
