    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capacity; Wireless communications; performance bounds; distributed sources; generalized beamforming; channel estimation; MIMO; training;

    Sammanfattning : The focus of this thesis is on channel estimation in wireless communication systems that employ multiple antennas.The thesis is divided into two parts, whereof the first part addresses theproblem of parameter estimation of distributed sources. Due to, e.g. LÄS MER

  3. 7. Influence of Fiber Nonlinearity on the Capacity of Optical Channel Models

    Författare :Kamran Keykhosravi; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinearity mitigation; Fiber optics; information theory; channel capacity; perturbation; achievable rate;

    Sammanfattning : The majority of today’s global Internet traffic is conveyed through optical fibers. The ever-increasing data demands has pushed the optical systems to evolve from using regenerators and direct-direction receivers to a coherent multi-wavelength network. LÄS MER

    Sammanfattning : The majority of today's global Internet traffic is conveyed through optical fibers. The ever-increasing data demands have pushed the optical systems to evolve from using regenerators and direct-direction receivers to a coherent multi-wavelength network. LÄS MER

  5. 9. Green Logistics through Modal Shift - exploring the role of the transport capacity contract

    Författare :Fredrik Eng Larsson; Teknisk logistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; green logistics; modal shift; mode choice; capacity management; supply chain contracting; intermodal transport;

    Sammanfattning : Among policy-makers in Europe the modal shift - a shift från polluting modes of freight transport to less polluting modes - has been a popular suggestion for reducing CO2-emissions of transportation. In particular, intermodal road-rail solutions, where a combination of road and rail transport is utilized to move trailers and containers, have been stressed as an important measure to reach de desired reduction in emissions.

  7. 10. Protonmotive coupling of energy conversion processes in photosyntetic bacteria : studies on membrane energization and photophosphorylation capacity

    Författare :Beston F. Nore; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fotosyntes;

    Sammanfattning : This work is a study on the membrane-bound inorganic pyrophosphatase and other energylinkedenzymes in the chromatophores from the photosynthetic bacterium Rhodospirillum rubrum.The membrane-bound inorganic pyrophosphatase is functionally similar to the well-known FiF0-ATP synthase.
