    Sammanfattning : The demand for higher data rates and efficient use of various resources has been an unquenchable thirst across different generations of cellular systems, and it continues to be so. Aggressive reuse of frequency resources in cellular systems gives rise to intercell interference which severely affects the data rate of users at the cell-edge. LÄS MER

  4. 3. Wireline Communications in a Wireless World

    Författare :Yezi Huang; Bredbandskommunikation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The whole society is digitalizing, filled with streaming services, cloud computing and an ambition of ubiquitous connectivity. To address the data demand, ultra-fast broadband, at the speeds of 1Gbps and more, is developed and deployed. Optical fibers have been long viewed as a future-proof carrier for the ultra-fast broadband. LÄS MER
