Abstract |
|
This paper presents DPD linearizer for the high power amplifiers. Conventional High power amplifiers operating with wideband signals must be backed off considerably from their peak power level in order to control out of band distortions, also known as ‘spectral re-growth’. Different linearization techniques are there to identify and compensate those non-linearities, like feedback, feed forward and digital pre-distortion. In this paper a low complexity volterra series method and indirect learning architecture for DPD has been considered to linearise a PA. |
