Abstract

Abstract : Nonlinearity in communication satellite payloads often severely degrades the downlink signal quality in such systems. A digital pre‐compensation technique to enhance digital predistortion performance in multicarrier satellite communication systems is presented. The proposed technique has been validated by simulations with an appropriate platform where excellent performance improvements have been measured. In addition, the implementation feasibility of this technique has been briefly demonstrated by means of a real‐time FPGA implementation.
