Title:
METHODS AND APPARATUSES FOR PERFOMING DIGITAL PREDISTORTION USING A COMBINTION MODEL
Document Type and Number:
WIPO Patent Application WO/2024/066098
Kind Code:
A1
Abstract:
Embodiments described herein relate to methods and apparatuses for performing digital predistortion, DPD, to provide a transmit signal, z(n) wherein the transmit signal, z(n), is for deriving one or more amplifier signals, zm(n), for driving one or more power amplifiers, wherein the one or more power amplifiers are associated with a respective one or more antenna elements. A method comprises: receiving a first signal, x(n); inputting the first signal, x(n), into a combination model, wherein the combination model comprises a machine learning, ML, model and a memory polynomial, MP, model; and outputting the transmit signal z(n), from the combination model.
