- Title
Design of Efficient Power Amplifier Models Using 16-QAM.
- Authors
Swaminathan, J.; Kumar, P.
- Abstract
In this paper a predistorter linearizer is designed to reduce the memory less and also memory effect in different power amplifier models. The proposed method is based on the joint working principle of RLS filter model (polynomial) which compensate intermodulates and the multi-level system excludes the trade-off between precision and adaptation speed. The Predistorter model is validated by utilizing the orthogonal frequency division multiplexing in 16-QAM modulation. The Matlab realization of the proposed system shows 32×-34× faster convergence time than predistorter based on conventional LMS model with same adaptation step.
