Summary:This paper presents a kind of Amplitude Adaptive Pre-distorter Design based on Sinusoid for High Power Amplifier (HPA). On the one hand, constraints are increased in the pre-distorter, and the efficiency, maximal export power and linearity into account at the same time; on the other hand, the ideal gain can be identified intelligently; and then, in order to resolve the problem of complicated algorithms realization and slow convergence, the pre-distorter is predigested, in which RLS is used directly. Finally, simulation testing based on the predigested model is carried out, and the results show the advantages of the technology.
