Abstract
A device for predistortion and pulse shaping filtering in a communication system includes input scaling means arranged for scaling an applied transmit symbol with an adaptable input gain scaling factor, and a pulse shaping filter and a predistortion unit arranged for applying on the input gain scaled transmit symbol in either order a filtering operation and a non-linear predistortion operation to obtain a predistorted signal. The non-linear predistortion operation is represented by a set of parameter values selectable among a plurality of given sets of parameter values. The predistortion unit is arranged for selecting the set of parameter values exploiting a given performance measure. The device includes output scaling means arranged for scaling the predistorted signal with an output gain scaling factor to obtain a transmit signal. The adaptable input gain scaling factor and the output gain scaling factor are precalculated values corresponding to the selected set of parameter values.
