A comparative study of wideband and dual-band digital predistortion architectures
In this paper, the wideband and dual-band architectures for digital predistorters (DPD) are compared in terms of the DPD models used, hardware implementations, complexity and linearization performance. The advantages and disadvantages of each architecture are outlined and hardware measurements are performed using an amplifier prototype to illustrate the differences between the two approaches.
