  1. 16. Dynamic nonlinear pre-distortion of signal generators for improved dynamic range

    University essay from Institutionen för teknik och byggd miljö

    Author : Suzan Jawdat; [2009]
    Keywords : Predistortion; IQ imbalance; Predistortion mirror distortion; Power amplifier deficiencies; Parsimonious predistorter structures; Predistorter properties; Training of the predistorter based on N-sequences of data.;

    Abstract : In this thesis, a parsimoniously parameterized digital predistorter is derived for linearization of the IQ modulation mismatch and the amplifier imperfection in the signal generator [1]. It is shown that the resulting predistorter is linear in its parameters, and thus they may be estimated by the method of least-squares. READ MORE

  3. 17. Still making faces, now also a dynamic one: An updated study of parameterized three-dimensional models of emotional facial expressions

    University essay from Lunds universitet/Institutionen för psykologi

    Author : Patrik Bratkovic; [2009]
    Keywords : animated; dynamic; emotion; faces; facial expressions; Poser; stimuli; Psychology; Psykologi; Social psychology; Socialpsykologi; Social Sciences;

    Abstract : With constant upgrades in 3d-modeling software, even previously functional and validated animated facial expressions can be updated. The present work seeks to provide such an additional upgraded set of tools for researchers to use interested in e.g. emotional facial expressions, and contains two experiments. READ MORE

  4. 18. IMPULSIVE NOISE MODELING AND COEXISTENCE STUDY OF IEEE 802.11 AND BLUETOOTH

    University essay from Institutionen för teknik och byggd miljö

    Author : Carl Karlsson; [2008]
    Keywords : coexistence; IEEE802.11; WLAN; WPAN; IEEE802.15; Middletons; interference;

    Abstract : This thesis describes the interference problem between IEEE 802.11 and Bluetooth. These well established communication standards are often used together simultaneously. Since both standards operate in the ISM-band at 2. READ MORE

  5. 19. Current Distribution in High RF Power Transistors

    University essay from Ämnesavdelningen för elektronik

    Author : Jihad EL-Rashid; Youssef Tawk; [2007]
    Keywords : Current Distribution in High RF Power Transistors;

    Abstract : To obtain the power levels required from high RF power transistors, the size of the chip has often to be made so large that inductance of electrical connections inside the package cannot be neglected. This may have the effect that various parts of the transistor chip are not connected exactly parallel, i.e. READ MORE

  6. 20. Greybox Identification and Control Design with Dymola

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Marco Bracci; [2005]
    Keywords : Technology and Engineering;

    Abstract : This Master Thesis has been done at the Department of Automatic Control, Lund Institute of Technology, and Dynasim AB, in Lund. Dynasim develops the simulation software called Dymola (Dynamic Modeling Laboratory). READ MORE
