slugPower Amplifier Linearization Using Digiital Predistortion
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 6
Abstract
For wideband or high power applications, the power amplifier exhibits memory effects, for which memoryless predistorters can achieve only limited linearization performance. The memory polynomial predistorter can correct both the nonlinear distortions and the linear frequency response that may exist in the power amplifier. It is a robust predistorter, which has demonstrated good performance on several nonlinear system models. The predistorter models considered in this paper include both even- and odd order nonlinear terms. Here, the benefits to include even-order nonlinear terms in both the baseband power amplifier and predistorter models are described.
