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

This paper proposes a new technique to identify the parameters of a digital predistorter
based on iterative learning control (ILC). ILC is a well-established control theory technique …

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

High-symbol-rate coherentoptical transceivers suffer more from the critical responses of
transceiver components at high frequency, especially when applying a higher order …

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 …

In this article, we describe a novel framework for digital predistortion (DPD)-based
linearization of strongly nonlinear millimeter-wave active antenna arrays. Specifically, we …

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 …

nonlinear distortion introduced filed on May 6, 2004, OW Pat No. 7,342,976, which is by …

This paper demonstrates an unprecedented novel neural network (NN)-based digital
predistortion (DPD) solution to overcome the signal impairments and nonlinearities in …

We demonstrate digital predistortion (DPD) using a novel, neural-network (NN) method to
combat the nonlinearities in power amplifiers (PAs), which limit the power efficiency of …
