Conventional radio-frequency (RF) power amplifiers operating with wideband signals, such
as wideband code-division multiple access (WCDMA) in the Universal Mobile …

The RF PA, as one of the most essential components in any wireless system, suffers from
inherent nonlinearities. The output of a PA must comply with the linearity requirement …

Full-duplex wireless communication is becoming an important research area because of its
potential for increasing spectral efficiency. The challenge of such systems lies in cancelling …

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 …

A novel digital predistortion (DPD) with an ultralow feedback sampling rate is proposed for
wideband wireless communications. Analytical groundwork is carried out to support the …

The high peak to average power ratio (PAPR) levels associated with multicarrier systems
require the use of linear power amplifiers (PA) with large dynamic range. Unfortunately …

We propose an efficient Wiener model for a power amplifier (PA) and develop a direct
learning predistorter (PD) based on the model. The Wiener model is formed by a linear filter …

We develop a new wideband digital feedback predistortion (WDFBPD) technique for
modulated signals with wide bandwidths by combining digital feedback predistortion …

This paper is concerned with digital predistortion (DPD) for linearization of radio frequency
(RF) high power amplifiers (PAs). We propose an adaptive scheme for selecting basis …

In this paper, a low-feedback-sampling-rate digital predistortion (DPD) method is proposed
for wideband wireless transmitters and radio-frequency power amplifiers (PAs). This DPD …
