A LUT Baseband Digital Pre-Distorter For Linearization
2012
This paper proposes a Look-Up-Table Digital Pre- Distorter (LUT DPD) for PA linearization with baseband predistorting procedure. Memory effect can be compensated with Memory Polynomial (MP) modelisation for the wideband applications. Measurements are realized on a PA ZFL-2500 driven by a modulated 16QAM signal with 3.84MHz bandwidth at the carrier frequency of 1.8GHz. The proposed solution achieves maximum ACPR reduction of 12.5dB and EVM correction of 3%.
