This paper presents an investigation into parameter adaptation in behavioralmodel--based digital predistortion for radio frequency power amplifiers. Anovel measurement setup framework that emulates real--time adaptation intransmitters is developed that allows evaluation of different parameters,configurations and adaptation algorithms. This setup relieves the need for fullfeedback loops for parameter adaptation while providing the flexibility neededin the design process of parameter adaptation.  Issues such as convergence speed, sensitivity to quantization noise in thefeedback loop and predistortion performance are investigated for some differentparameter update algorithms using the proposed measurement setup. The approachpresented in this paper allows the possibility to analyze different aspects ofdigital predistortion adaptation algorithms, and is an important enabling stepfor further research on parameter adaptation before the real--time hardware isimplemented for use.
