  2. 6. Physics at the High-Energy Frontier : Phenomenological Studies of Charged Higgs Bosons and Cosmic Neutrino Detection

    Author : Oscar Stål; Gunnar Ingelman; Johan Rathsman; Jonathan Ellis; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; particle physics; Standard Model; beyond the Standard Model; supersymmetry; Higgs physics; charged Higgs boson; LHC; flavour physics; ultra-high-energy neutrinos; Askaryan effect; radio detection; lunar satellites; Elementary particle physics; Elementarpartikelfysik; högenergifysik; High Energy Physics;

    Abstract : The Standard Model of particle physics successfully describes present collider data. Nevertheless, theoretical and cosmological results call for its extension. A softly broken supersymmetric completion around the TeV scale solves several of the outstanding issues. Supersymmetry requires two Higgs doublets, leading to five physical Higgs states. READ MORE

  4. 7. ROBUST DETECTION AND SPECTRAL ANALYSIS OF SIGNALS WITH APPLICATIONS IN SPECTROSCOPY

    Author : Naveed Butt; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Detection; NQR; NMR; Raman Spectroscopy; Spectral Analysis.;

    Abstract : Modern spectroscopic techniques, such as nuclear quadrupole resonance (NQR), nuclear magnetic resonance (NMR), and Raman spectroscopy, rely heavily on statistical signal processing systems for decision making and information extraction. The first part of this thesis introduces novel robust algorithms for detection, estimation, and classification of signals obtained through these spectroscopic techniques. READ MORE

  5. 8. Sub-Nyquist Sampling Impulse Radio UWB Receivers for the Internet-of-Things

    Author : Qin Zhou; Hannu Tenhunen; Li-Rong Zheng; Qiang Chen; Kari Halonen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultra-Wideband; impulse radio; receiver; energy detection; compressed sensing; sub-Nyquist sampling; Internet-of-Things; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : In the era of Internet-of-Things, the demand for short range wireless links featured by low-power and low-cost, robust communication and high-precision positioning is growing rapidly. Impulse Radio Ultra-Wideband (IR-UWB) technology characterized by the transmission of sub-nanosecond pulses spanning up to several GHz band with extremely low power spectral density emerges as a promising candidate.

    Abstract : With the advent and widespread applications of high data-rate wireless services and devices, two of the fundamental resources in wireless communication have become extremely important and are scarce. These two resources are bandwidth and energy respectively. READ MORE

  7. 10. On Modulation and Detection Schemes for Low-Complexity Impulse Radio UWB Communications

    Author : Muhammad Gufran Khan; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UWB; RAKE; Transmitted reference; Energy detection; Channel measurements; BPPM;

    Abstract : Due to wealth of advantages offered by short range ultra wideband (UWB) technology, such as capacity improvement, fading reduction and localization, it has gathered a considerable attention. Distinct UWB qualities also pose many system design challenges like difficulties in using digital processing, complex channel estimation and different propagation characteristics. READ MORE
