Linearization of Power Amplifiers by digital predistortion (DPD) for applications in tactical communications and digital diffusion

, 2015
L'amplificateur de puissance est le module le plus critique dans les équipements de communication radio. Il détermine la qualité de la liaison par sa linéarité et a une contribution conséquente dans la consommation de l'émetteur ; environ 60% de l'énergie consommée est consacré à l'amplification.

Power Amplifiers Linearization Based On Complex Gain Memory Predistortion [PDF]

, 2010
Power Amplifiers (PAs) are important components in communication systems and are nonlinear. The nonlinearity creates out of band distortion beyond the signal bandwidth, which interferes with adjacent channels.
