Concurrent Multiband Linearization for Power Amplifiers With Intermodulation Distortions

This letter investigates digital predistortion (DPD) models for concurrent multiband (MB) transmitters, considering intermodulations (IMDs) fully and partially overlapping with in-band carriers. In order to mitigate the issue of increasing complexity of IMD terms construction, a novel prefrequency s...
