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

    Författare :Kia Wiklundh; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. On Performance of Digital Radio Receiver in Non-Gaussian Interference

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

    Sammanfattning : Interference from electrical equipment can degrade a co-located digital radio receiver severely. To avoid this performance degradation it is necessary to have estimation methods to predict the influence from an interference environment on a radio receiver in advance. LÄS MER

  5. 4. Bounds on the Performance of PSK Block Codes

    Författare :Efraim Laksman; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In wireless communication, the minimum Euclidean distance between codewords is a major factor for the ability to correct errors in messages, and it is of interest to maximize the minimum Euclidean distance. The thesis improves previously established general upper bounds on minimum Euclidean distance of phase shift keying block codes. LÄS MER

  7. 5. On interference suppression techniques for communication systems

    Författare :Hongxia Zhao; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CDMA; QPSK; fixed-point implementation; DQPSK; rapid single flux quantum RSFQ ; MUD; unequal BER; fiber-optic communications; unequal SER; ISI;

    Sammanfattning : The work presented in this thesis concerns interferencesuppression techniques in two different communication systems.In the first part we study fiber-optic systems with practical non-ideal transmitters and receivers, which give rise to intersymbol interference (ISI). LÄS MER
