Abstract
Method and device(s) for performing digital predistortion, 'DPD', on multiple digital input signals to be transmitted in different frequency bands, respectively, of a wireless communication network. The frequency bands being associated with linearization bandwidths, respectively, for application of the DPD. Said DPD is performed in two parts: A first DPD part with a first DPD performed for each of said input signals over the signal's full linearization bandwidth using a first set of non-linear terms and basis functions. A second DPD part where another, second DPD is performed for each of said input signals over the signal's linearization bandwidth except where the linearization bandwidth covers the signal's frequency band using another, second set of non-linear terms and basis functions. Predistorted multiple digital output signals are provided based on both of said performed DPDs.
