Digital predistortion (DPD) is the linearization technique most often used to cope with the
inherent tradeoff between linearity and efficiency in power amplifiers (PAs). Adaptation is …

Digital predistortion (DPD) is one of the most effective techniques to mitigate the distortions
caused by power amplifier (PA) nonlinearity and memory effects. As the input signal …

Over at least the last two decades, digital predistortion (DPD) has become the most common
and widespread solution to cope with the power amplifier's (PA's) inherent linearity-versus …

Power amplifiers (PAs) are key components of mobile base stations. In the last decade, the
power efficiency of PAs for 3G/4G mobile base stations has risen to over 50% as a result of …

In this paper, a novel decorrelation-based concurrent digital predistortion (DPD) solution is
proposed for dual-band transmitters (TXs) employing a single wideband power amplifier …

This paper presents a new 3-D behavioral model to compensate for the nonlinear distortion
arising in concurrent dual-band (DB) Envelope Tracking (ET) Power Amplifiers (PAs). The …

As wireless communication standards evolve to support ever-higher data rates, the required
linearity and bandwidth must increase, which leads to higher energy consumption [1]. The …

Under the scenario of noncontiguous carrier aggregation with closely spaced multiple
bands, the interband modulation products after power amplifying will overlap with the bands …

Conventional digital predistortion (DPD) techniques are facing the challenge of complexity
in the fifth generation (5G) and beyond concurrent dual-band terminal transmitters. This …

Design of high-efficiency power amplifier (PA) is one of the key challenges to realize green
radios, wherein digital predistortion (DPD) is deployed to reduce the PA's power back-off …
