Abstract
An adaptive digital predistortion scheme, based on the amplitude-and-phase predistortion concept, is considered for the linearisation of microwave pow er amplifiers in high-data-rate radio relay links. The algorithm is thoroug hly assessed and compared to a digital predistortion scheme recently propos ed in the literature, assuming Linearisation accuracy, adaptation speed and implementation complexity as merit criteria. The proposed predistorter pro ves to be considerably faster than the other scheme, though exhibiting appr oximately the same accuracy and a reduced complexity.
