This work presents a measurement setup for digital predistortion which utilizes single channel direct RF undersam-pling, removing the need for mixer-based analog downconversion. The setup is tested on a commercial power amplifier, with a 10 MHz QPSK-modulated input signal, yielding an improvement in normalized mean square error from 0.0087 to 4.54e-04.

Abstract
This work presents a measurement setup for digital predistortion which utilizes single channel direct RF undersam-pling, removing the need for mixer-based analog downconversion. The setup is tested on a commercial power amplifier, with a 10 MHz QPSK-modulated input signal, yielding an improvement in normalized mean square error from 0.0087 to 4.54e-04.File in questo prodotto:
