Abstract
A memory polynomial model (MPM) is adopted to describe the characteristics of GaN power amplifiers (GaN-PA) in orthogonal frequency division multiplexing (OFDM) communication systems, and the RLS algorithm is used to estimate the MPM parameters in on-line manner. The MPM with odd-even orders is considered in choosing models. Furthermore, the orders and memory length of MPM are decided by the final prediction error (FPE). Finally, an adaptive pre-distorter is designed besed on the achieved MPM, and its effectiveness is proved by numerical simulation.
