This paper presents a novel two-dimensional multi-branch model for the dynamic behavioral modeling and digital predistortion of dual-band power amplifiers (PAs) operated in concurrent multi-band, multi-standard mode. The model performance was validated by linearizing a dual-band class AB PA, driven by different bandwidth LTE and WCDMA signals.

Implementing crest factor reduction (CFR) by offsetting digital predistortion (DPD) coefficients
2012 Workshop on Integrated Nonlinear Microwave and Millimetre-wave Circuits, 2012A combined approach to digital predistortion (DPD) and crest factor reduction (CFR) is proposed. The new CFR is structured similar to DPD and is implemented by introducing a steady-state offset into the DPD coefficients. The DPD and CFR coefficients are estimated using separate adaptive processes but applied to the transmission path in a common module.

2016 87th ARFTG Microwave Measurement Conference (ARFTG), 2016
Computationally efficient estimation of digital predistortion (DPD) coefficients for memory polynomial, gain polynomial, and pruned Volterra series models is proposed. In all three cases, the basis waveforms within the estimator are specified in the frequency domain as a function of memoryless waveforms and delay operators, thereby reducing the number ...

2017 IEEE Topical Conference on RF/Microwave Power Amplifiers for Radio and Wireless Applications (PAWR), 2017
Strategies for reducing the number of basis waveforms used in a Volterra series model for digital predistortion (DPD) of RF power amplifiers (PAs) are proposed. Simple DPD models are generalized so that elemental terms within the Volterra series are grouped together or pruned.
