Abstract
A new memory polynomial/look-up table (MP/LUT) baseband digital predistorter (DPD) based on direct learning architecture is proposed for power amplifier (PA) linearisation in wideband applications. The main advantages of this DPD are high simplicity and the robust modellisation of the PA´s behaviour provided by the MP model. Measurements are realised on a test bench using the PA ZFL-2500 driven by a 16QAM modulated signal with 3.84´MHz bandwidth at the carrier´s centre frequency of 1.8´GHz.
