  1. 1. Combating Intersymbol Interference and Cochannel Interference in Wireless Communication Systems

    Detta är en avhandling från Karlskrona : Blekinge Institute of Technology

    Författare :Ronnie Gustafsson; ; [2003]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ISI; CCI; wireless systems; beamforming; beam; simulation; fading; equalizer; channel; smart antenna; antenna array; recursive least squares RLS ; adaptive algorithms; blind algorithms;

    Sammanfattning : Over the last decade the world has witnessed explosive growth in the use of wireless mobile communications. Looking around we find users with mobile phones, wireless PDAs, pagers, MP3 players, and wireless headphones to connect to these devices - a small testament of the impact of wireless communications on our daily lives.

  2. 2. Reduced Receivers for Faster-than-Nyquist Signaling and General Linear Channels

    Detta är en avhandling från Tryckeriet i E-huset, Lunds universitet

    Författare :Adnan Prlja; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital data transmission; receivers; decoders; channel modeling; intersymbol interference; ISI; MIMO; Faster-than-Nyquist signaling; complexity reduction; observation models; BCJR algorithm; turbo equalization; iterative detection; channel shortening;

    Sammanfattning : Fast and reliable data transmission together with high bandwidth efficiency are important design aspects in a modern digital communication system. Many different approaches exist but in this thesis bandwidth efficiency is obtained by increasing the data transmission rate with the faster-than-Nyquist (FTN) framework while keeping a fixed power spectral density (PSD).

  3. 3. On interference suppression techniques for communication systems

    Detta är en avhandling från Tryckeriet i E-huset, Lunds universitet

    Författare :Hongxia Zhao; [2008]
    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

  4. 4. Glaucoma Diagnostics

    Detta är en avhandling från Wiley-Blackwell

    Författare :Sabina Andersson; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; POAG – glaucoma – diagnostic accuracy – screening – subjective assessment – population-based – GDx VCC – OCT – HRT – FDT – ONH assessment – CME – ANN – artificial neural network – visual field assessment;

    Sammanfattning : This thesis addresses several aspects of glaucoma diagnostics from both a clinical and a screening perspective. New instruments for diagnosing glaucoma have been developed over the past years, but little information is available regarding their performance as screening methods and their usefulness in ordinary clinical practice.
