Résumé

In this paper, an new methodology for modeling the nonlinearity in power amplifier (PA) with memory is presented. It is based on the construction of a basis of orthogonal lookup-tables using SVD technique. It provides an effective and systematic way of representing and digitizing dynamic kernels in PA models that account for memory. It is shown that this procedure guarantees a high accuracy in PA intermodulation (IMD) prediction.
