| Popis: | In this letter, an efficient predistortion scheme is proposed to compensate imperfections in a satellite channel due to the nonlinear power amplifier and the output channel filter. The predistorter is a Wiener system consisting of the linear and nonlinear components, which are trained independently. The predistorter is well suited to systems where the data bits are generated onboard the satellite. The proposed setup effectively compensates the distortions and has lower complexity compared with other strategies. Refereed/Peer-reviewed |
