Digital Predistortion


The high peak-to-average power ratio (PAPR) of future wireless communication signals imposes stringent requirements on the linearity of RF units. RF power amplifiers (PA’s) introduce nonlinear distortion if operated in a highly power efficient regimes. Therefore, behavioral modeling of nonlinear power amplifiers is an essential step towards the development linearization schemes to overcome nonlinear distortion. Predistortion is the most common approach because of its simplicity and therefore its lower cost. Predistortion can be implemented at RF, IF or at baseband. Baseband pre-distortion methods are becoming popular because they provide a balanced trade-off between cost and performance.
