  2. 2. A new approach for considering the interference impact on digital radio systems from complex interference environments

    University dissertation from Institutionen för datavetenskap och elektronik

    Author : Kia Wiklundh; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; minimum shift keying; class A; amplitude probability distribution; bandwidth conversion; Gaussian approximation; emission; non-Gaussian interference; performance estimation; man-made noise; measurement; emission requirements; micro-wave oven; MSK; coding gain; APD; interference;

    Abstract : Interference from electrical equipment can severely degrade aco-located digital radio receiver. To avoid such performance degradation, it isnecessary to have estimation methods to predict the influence of an interferenceenvironment on a radio receiver. READ MORE

  3. 3. Design Aspects of Fully Integrated Multiband Multistandard Front-End Receivers

    University dissertation from Kista : Mikroelektronik och informationsteknik

    Author : Adiseno; KTH.; [2003]
    Keywords : low-noise amplifier; mixer; RF front-end; wireless receiver; noise figure; linearity; bandwidth; dual-loop feedback;

    Abstract : In this thesis, design aspects of fully integrated multibandmultistandard front-end receivers are investigated based onthree fundamental aspects: noise, linearity and operatingfrequency. System level studies were carried out to investigatethe effects of different modulation techniques, duplexing andmultiple access methods on the noise, linearity and selectivityperformance of the circuit.

  4. 4. Oesophageal manometry : design and evaluation of measurement systems

    University dissertation from Karlshamn : Lagerblads Tryckeri AB

    Author : Per Ask; Linköpings universitet.; Linköpings universitet.; [1978]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN;

    Abstract : The aim of this study was to investigate the technical characteristics of oesophageal manometry systems and to improve the performance of these systems.The investigation of the characteristics of oesophageal manometry systems with non-perfused catheters or catheters perfused with a flow generated by a syringe pump did not show properties which fullfilled the requirements for accurate pressure measurements.

  5. 5. Measurement Techniques for Characterization of Power Amplifiers

    University dissertation from Stockholm : KTH

    Author : David Wisell; Högskolan i Gävle.; KTH.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Electrical engineering; electronics and photonics Electronics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elektronik; TECHNOLOGY Information technology Signal processing; TEKNIKVETENSKAP Informationsteknik Signalbehandling;

    Abstract : In this thesis a sampling time domain measurement system primarily intended for measurements on radio frequency power amplifiers is discussed. The need for such a measurement system is established. Impairments due to non-ideal measurement instruments are discussed as well as methods to compensate for these impairments. READ MORE
