Pareto-Optimal Multimetric Model Extraction for Digital Predistortion of RF Power Amplifiers for Error Spectrum Redistribution

In complex spectrum coordination scenarios in wireless communications, different frequency regions may have distinct linearity requirements. Digital predistortion (DPD), a widely used linearization technique, must address these varying needs properly by effectively redistributing the linearity error...
