TL;DR
This paper presents an experimental validation of a sequence-wise predistorter to accurately evaluate geometrically shaped 128-QAM signals, ensuring correct constellation point transmission during testing.
Contribution
It introduces a novel predistorter method specifically designed for evaluating geometrically shaped constellations in high-order QAM systems.
Findings
Predistorter effectively compensates for transmitter nonlinearities.
Accurate transmission of geometrically shaped 128-QAM points achieved.
Improved evaluation accuracy demonstrated through experiments.
Abstract
A predistorter for transmitter nonlinearities is applied to the evaluation of a geometrically shaped constellation, such that constellation points are transmitted correctly during the evaluation of the geometrically shaped constellation.
