An efficient simplified behavioral model for RF power amplifiers

We present efficient simplified behavioral models for power amplifier (PA) and its digital predistorter (DPD). Even though the many promising models have been proposed, more rigorous derivation and improvements in terms of performance and complexity are needed. In this paper, new approach is attempted to tackle the above. After building basis set based on simple rules, the new efficient and simplified models are derived by adding only the appropriate basis into the previous composite bases. The experimental results show that the proposed models for the PA and DPD outperform the conventional models.
