Predistortion linearization is by far the most widely used form of linearization and is most …

Development of 5G networks requires a substantial increase to both spectral and power
efficiency of transmitters. It is known that these two parameters are subjected to a mutual …

This paper presents the design and characterization of a load modulated balanced amplifier
for telecom base station applications adopting a novel mode of operation. The theory of …

The polynomial model is commonly used in power amplifier (PA) modeling and predistorter
design. However, the conventional polynomial model exhibits numerical instabilities when …

This paper proposes a new behavioral model to treat memory effects in nonlinear power
amplifiers (PAs). Phenomena such as asymmetries in lower and upper intermodulation …

The adaptive nonlinear predistorter is an effective technique to compensate for the nonlinear
distortion existing in digital communication and control systems. However, available …

Over the past 25 years or so there has been much interest in the use of digital pre-distortion
(DPD) techniques for the linearization of RF and microwave power amplifiers. In this paper …

Digital predistortion is one of the most cost effective ways among all linearization
techniques. However, most of the existing designs treat the power amplifier as a memoryless …

With the growing complexity of personal mobile communication systems demanding higher
data-rates and high levels of integration using low-cost CMOS technology, overall system …

This paper presents a method for pruning power amplifier (PA) behavioral models and
digital predistorters based on compressed sampling theory. Using this method, the number …
