Increasing demand for spectral efficiency in radio communications makes multilevel linear
modulation schemes such as Quadrature Amplitude Modulation more and more attractive …

Future communications systems will have to integrate multiple radio technologies in order to
support a large number of wireless standards (cellular technology, WMAN, WLAN and …

Linear amplifiers are becoming increasingly important as the drive for more spectrally
efficient systems continues. As the number of people wishing to use mobile communication …

" Distortion in RF Power Amplifiers explains that by minimizing memory effects, it is possible
to use simple linearizers, such as analog predistortion, and still achieve sufficient …

Even though high linearity is crucial in modern mobile communications, it is not desirable to
use the most linear power amplifier types due to their poor efficiency. Predistortion is a …

Spectral efficiency is increasingly important in today's mobile communications. The non-
constant envelope (high peak-to-average ratio) digital modulation schemes used in many …

This paper presents experimental results for the adaptive baseband predistortion technique
proposed in (Cottais, 2004). The obtained results show the real capacity of the method to …

The purpose of this Major Qualifying Project was to develop and evaluate a digital baseband
predistortion approach for radio frequency power amplifiers (RFPA). We also aimed to …

Background The demand for high data rates and stringent Federal Communications
Commission (FCC) requirements have driven the need for spectrally-efficient modulation …

Power amplifiers are used extensively in many TV signal transmissions with an important
requirement of exceptional linearity. One efficient approach can be reached by introducing …
