    Abstract : Since they appeared, wireless technologies have deeply transformed our society. Today, wireless internet access and other wireless applications demandincreasingly more traffic. However, the continuous traffic increase can be unbearableand requires rethinking and redesigning the wireless technologies inmany different aspects. READ MORE

  2. 2. Design and Optimization of Wideband Hat-Fed Reflector Antenna with Radome for Satellite Earth Station

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Erik G Geterud; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antenna feeds; satellite earth stations.; optimization; corrugated surfaces; radomes; reflector antennas;

    Abstract : This thesis presents the development of a hat-fed refector antenna with radome to be used as satellite earth station. The antenna with self supported feed is relatively compact, circular symmetric and with low cross polarization. To achieve optimum performance over the satellite Ku-band,covering 10.75-14. READ MORE

  3. 3. Frequency Transfer Techniques and Applications in Fiber Optic Communication Systems

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Abstract : Modern society is dependent on communications and the developments of these increases constantly through a seemingly endless demand for communication services and thereby synchronization and time. This is confirmed by a vast range of research on communications, irrespective of technology and protocol. READ MORE

  4. 4. Parameter Estimation for Mobile Positioning Applications

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Parinaz Kasebzadeh; Linköpings universitet.; Linköpings universitet.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The availability and reliability of mobile positioning algorithms depend on both the quality of measurements and the environmental characteristics. The positioning systems based on global navigation satellite systems (GNSS), for example, have typically a few meters accuracy but are unavailable in signal denied conditions and unreliable in multipath environments.
