With the explosive growth of the smartphone and tablet markets, wide bandwidth voice and
data communication have become ubiquitous. Users expect to use their wireless portable …

This paper proposes a robust model for the accurate behavioral modeling and digital
predistortion (DPD) of wideband radio-frequency power amplifiers (PAs). It is constructed …

The behavior of power amplifiers (PAs) driven by concurrent dual-band signals is analyzed
theoretically in this paper. According to the analysis, the impedance matching at …

This paper reports a novel digital predistortion (DPD) scheme for concurrent tri-band power
amplifiers (PAs). The proposed tri-band DPD is based on a pruned Volterra model that takes …

A concurrent dual-band digital predistortion (DPD) system is presented to compensate for
the nonlinearity of the radio-frequency power amplifiers (PAs) driven by a concurrent dual …

This paper proposes a novel three-dimensional digital predistorter (3D-DPD) suitable for
compensating nonlinear distortion in dual-band (DB) envelope tracking (ET) power …

A novel generalized two dimensional (2-D) digital predistortion (DPD) architecture for
concurrent dual-band transmitters is presented. The proposed architecture is based on …

This paper proposes a new method to prune the kernels of 2-D digital preditortion (2-D-
DPD) model. The conventional 2-D-DPD model is rewritten as a new form with each of the …

This letter proposes a modified 2-D memory polynomial predistorter for concurrent dual
band power amplifiers, which is tolerant to the time misalignment between the two bands …

In multi-carrier transmitters, nonlinear characteristic of power amplifiers (PAs) results in intra-
band distortion and interband distortion. The intra-band distortion exists in most singlecarrier …
