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 …

This paper proposes three novel models for behavioral modeling and digital pre-distortion
(DPD) of nonlinear 2× 2 multiple-input multiple-output (MIMO) transmitters in the presence of …

Most conventional wideband digital predistortion (DPD) techniques require the use of a very
high-speed analog-to-digital converter (ADC) in the feedback path. This paper proposes a …

This paper proposes an error variation ranking (EVR)-based pruning method to reduce the
complexity of memory polynomials (MPs) for power amplifier behavioral modeling. During …

Power Efficiency in Broadband Wireless Communications focuses on the improvement of
power efficiency in wireless communication systems, especially of mobile devices …

This paper studies the linearity of dual-input Doherty power amplifiers. We propose a
linearization scheme that uses a combination of an efficiency-optimized static splitter and a …

The recently-proposed multi-dimensional digital predistortion (DPD) technique is
experimentally investigated in terms of nonlinearity order, memory length, oversampling …

This letter presents a new dual band Volterra-based model suitable for the linearization of
envelope tracking (ET) power amplifiers (PAs) driven concurrently with two widely spaced …

This paper reports an envelope tracking (ET) transmitter architecture for multi-band/widely-
spaced carrier signals. Due to the bandwidth limitations of the envelope modulator, the …

In this paper, an output-controllable digital predistortion (DPD) technique is proposed to
partially inverse the nonlinear behavior of RF power amplifiers (PAs). Compared to the …
