Abstract(in English) | A novel feedback technique for reducing the cost of digital Predistorter (DPD) is studied. Spectrum-folding scalar-feedback (SF-SFB) DPD which monitors the in-phase nonlinear signal can be used for complex modulation signals with uniformly distributed phases. It has nonlinear compensation performance equivalent to conventional DPD which monitors complex signal for power amplifier without memory effect. In this paper, the nonlinear compensation performance of SF-SFB DPD with memory effect is evaluated by computer simulation and experiment. It has validated that SF-SFB DPD sufficiently compensates nonlinearity with memory effect. |
