Measurement setup for digital predistortion adaptation

Övrigt konferensbidrag, 2011

This paper proposes a measurement setup to emulate adaptive predistortion of power amplifiers without real--time hardware circuitry. The method consists of utilizing repeated measurements in a matter that keeps the power amplifier in a state similar to the state it would be in using real--time adaptation hardware. This method provides a way to test and compare amplifier predistortion techniques without the need for expensive and complicated hardware in the feedback loop.
