  1. 1. Faster than Nyquist Signaling with Spatial Coupling

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Haoran Liu; Lingwei Zhang; [2022]
    Keywords : Technology and Engineering;

    Abstract : The emergence of the Faster-Than-Nyquist signaling (FTN) technology has im- proved the tight spectrum resources by compressing the transmission interval between adjacent pulses. In a natural environment, data transmission via a wire- less medium and through multi-path, at a high data rate, the leakage of these paths among symbols can cause severe inter-symbol interference (ISI).

  3. 2. Low complexity algorithms for faster-than-Nyquistsign : Using coding to avoid an NP-hard problem

    University essay from KTH/Optimeringslära och systemteori

    Author : Emil Ringh; [2013]
    Keywords : ;

    Abstract : This thesis is an investigation of what happens when communication links are pushed towards their limits and the data-bearing-pulses are packed tighter in time than previously done. This is called faster-than-Nyquist (FTN) signaling and it will violate the Nyquist inter-symbol interference criterion, implying that the data-pulsesare no longer orthogonal and thus that the samples at the receiver will be dependent on more than one of the transmitted symbols.

  4. 3. Noise sources in the electric field antenna on the ESA JUICE satellite

    University essay from

    Author : Elias Odelstad; [2013]
    Keywords : JUICE; noise; quasi-thermal noise; QTN; Nyquist noise; shot noise; Langmuir probes; electric field probes;

    Abstract : The noise in the Langmuir Probe and Plasma Wave Instrument (LP-PWI) on board ESA:s future Jupiter satellite JUICE (Jupiter ICy Moons Explorer) was investigated. Thermal Johnson-Nyquist noise and shot noise, caused by fluctuations in the probe-plasma currents, were combined with the quasi-thermal noise (QTN) due to thermal fluctuations in the electric field in the plasma, using a small signal equivalent circuit model.

  6. 5. Delay-Stability of Power Control in Wireless Networks

    University essay from KTH/Reglerteknik

    Author : Benjamin Heinrich; [2011]
    Keywords : ;

    Abstract : In this thesis, we investigate the stability of uplink power control algorithms in wireless networks. We derive an abstract block-diagram model of the power-control loop similar to the model in [6]. READ MORE
