Abstract

This paper proposes a technique that jointly compensates the amplifier nonlinearity and quadrature modulation (QM) errors. The proposed method is derived based on the indirect learning architecture, which has been originally developed for the predistortion (PD). The proposed compensator updates the parameter vector based on the recursive least squares (RLS) criterion. The advantage of the proposed adaptive technique is demonstrated through computer simulation
