  1. 21. Interference Mitigation and Synchronization for Satellite Communications

    Författare :Joel Grotz; Björn Ottersten; Dirk Slock; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

    Sammanfattning :  Within this thesis, the satellite broadcast scenario of geostationary satellites is reviewed. The densely crowded geostationary arc in the common broadcast frequencies may create significant interference from adjacent satellites (ASI). LÄS MER

  3. 22. Quantum interference effects in attosecond photoionization dynamics

    Författare :David Busto; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Attosecond; Photoionization; Interferometry;

    Sammanfattning : The interaction of extreme ultraviolet light with matter can lead to the emission of an electron in a process known as photoionization. The electron wavepacket (EWP) created in the continuum propagates on the ionic potential, resulting in a delay compared to an EWP propagating freely. LÄS MER

  4. 23. Resource Allocation on the MISO Interference Channel

    Författare :Johannes Lindblom; Erik G. Larsson; Mats Bengtsson; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The need for wireless communications has increased during the last decades. To increase the data rates of the communication links there is a need of allocating larger frequency bands. These bands are strictly regulated and the majority of the frequencies are allocated to licensed systems. LÄS MER

  5. 24. On Interference Management With Incomplete Side Information

    Författare :Efthymios Stathakis; Mikael Skoglund; Marios Kountouris; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The evolution towards next generation wireless networks has to serve high expectations and demands, therefore ongoing research has to tackle problems that have hitherto received less attention. A decisive step in this direction is to consolidate cohabitation paradigms into the envisioned communication protocols. LÄS MER

  7. 25. The Information-Theoretic Cost of Learning Fading Channels

    Författare :Wei Yang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiple antennas; finite blocklength; outage capacity; block-fading channel; Shannon capacity; quasi-static fading;

    Sammanfattning : Recent results in communication theory suggest that significant throughput gains in wireless fading networks can be achieved by exploiting network coordination (e.g., CoMP, network MIMO, and interference alignment), provided that each node in the network has perfect channel knowledge.
