    Författare :Mahmoud Zaher; Emil Björnson; Marina Petrova; Mikael Sternad; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cell-free massive MIMO; power allocation; sum-SE maximization; proportional fairness; spectral efficiency; deep learning; handover; cluster formation; pilot assignment; unknown interference; outage; multiuser MIMO.; Cellfri massiv MIMO; effektreglering; summa-SE-maximering; proportionell rättvisa; spektraleffektivitet; djupinlärning; överlämning; klusterbildning; pilottilldelning; okända störningar; avbrottsnivå; MIMO för flera användare.; Datalogi; Computer Science;

    Sammanfattning : The ever-growing demand of wireless traffic poses a challenge for current cellular networks. Each new generation must find new ways to boost the network capacity and spectral efficiency (SE) per device. A pillar of 5G is massive multiple-input-multiple-output (MIMO) technology. LÄS MER

  4. 3. Channel Estimation and Self-Interference Suppression for MIMO Relaying Systems

    Författare :Panagiota Lioliou; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; estimation; expectation-maximization EM ; half-duplex; Bayesian; multiple-input multiple-output MIMO ; Cramer-Rao Bound CRB ; full-duplex; relays; performance analysis; Kalman filter KF ; self-interference.; Amplify-and-forward AF ; least squares LS ;

    Sammanfattning : Recently, the introduction of relaying nodes in wireless channels has been identified as a promising technique for providing broader coverage, higher transmission rates, and increased reliability. Moreover, when the concept of relaying systems is combined with that of multiple-input multiple-output (MIMO) technology, thesystem performance can be further improved by exploiting the spatial dimension.

  5. 4. Detection and quantification of lipid-mediated siRNA delivery to the cytosol

    Författare :Hampus Hedlund; Tumörmikromiljö; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RNA Interference; RNA Therapeutics; Endosomal Escape; Lipid Mediated Delivery; Live-Cell Imaging;

    Sammanfattning : Cancer is one of the leading causes of death globally. Novel therapeutics is urgently needed to advance treatment, especially for generalized disease where current treatment options have a poor prognosis. In particular, targeted therapy that can address genetic changes would be of great value. LÄS MER

  7. 5. Severe angina pectoris and spinal cord stimulation. Long-term effects and safety aspects

    Författare :Olof Ekre; Göteborgs universitet; []
    Nyckelord :Angina pectoris; Epidemiology; Spinal cord stimulation; Quality of life; Mortality; Health care costs; Electromagnetic interference; Placebo effects;

    Sammanfattning : Refractory angina pectoris has been defined as coronary artery disease and severe angina, where standard pharmacological and invasive treatment possibilities are exhausted. The epidemiology of this condition is virtually unknown.During the last few decades, additional treatment options have evolved for this condition. LÄS MER
