Abstract :
The telecommunication area is now highly involved in the "green technologies", proposing systems with limited power consumptions. As the power amplifier is, in a transmission chain, the most power dispersive element, it seems judicious to investigate solutions allowing an optimization of its throughput. A possible solution aims at distorting the signal just before amplification thanks to a predistorter, updated with an adaptive algorithm. The association of the predistorter and the power amplifier should then appear as linear as possible. This paper proposes a comparative study of the algorithms performance in a DVB-T context. From these simulations considering memoryless and memory power amplifiers, the algorithms performance in the correction of nonlinear effects is shown and analyzed.
