Amplification of 4-, 8-, 16-, 32- and 64-QAM through the Memory Polynomial-Model as Special Case of the Volterra Series Implemented in a RF Satellite Link

摘要

In this paper is fully proved the behavior of the Volterra Series through a Memory-Polynomial Model (MPM) excited by QAM Input and implemented in an Radio Frequency Satellite Link (RFSL). Several sequences of 4-, 8-, 16-, 32 and 64-QAM Inputs were introduced to the MPM. The MPM as special truncation of the Volterra Series showed a orrect behaviour for each QAM Input and the RFSL was able to stabilize the losses on the radio link and interferences introduced by the Satellite Link caused mainly by the transmission distance simulated by Simulink. The full system is able to compensate these perturbations caused by a normal satellite link.
