  2. 1. Advanced Transmitter Architectures Based on Switch Mode Power Amplifiers

    Author : MUSTAFA ÖZEN; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combiner; SMPA; Bandwidth; class-E; outphasing; energy efficiency;

    Abstract : Nowadays the main driving parameters for the research in radio transmitters in wireless infrastructure are energy efficiency, frequency agility, and integration.This thesis presents new solutions at the device waveform-, circuit-, and transmitter level which exploit the inherent high efficiency potential of switch-mode power amplifiers (SMPAs) for realization of energy efficient, wide-band, highly integrated transmitters for wireless communication applications.

  6. 4. Estimation of Inverse Models Applied to Power Amplifier Predistortion

    Author : Ylva Jung; Martin Enqvist; Lennart Ljung; Torkel Glad; Mikael Sternad; Linköpings universitet; []
    Keywords : ;

    Abstract : Mathematical models are commonly used in technical applications to describe the behavior of a system. These models can be estimated from data, which is known as system identification. Usually the models are used to calculate the output for a given input, but in this thesis, the estimation of inverse models is investigated. READ MORE

  7. 5. Digital Baseband Modeling and Correction of Radio Frequency Power Amplifiers

    Author : Per Landin; Peter Händel; Magnus Isaksson; Wendy Van Moer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Aspects related to behavioral modeling and correction of distortions for radio frequency (RF) power amplifiers (PAs) are treated in the thesis.    When evaluating the performance of a behavioral model it is important to, first of all, use an evaluation criterion, and second, make sure that the criterion actually tells something about the behavior one wishes to describe.
